     Gerard Klauer Mattison & Co., Inc. has been retained to act as agent for us
in connection  with the arrangement of this  transaction.  We have agreed to pay
Gerard Klauer  Mattison & Co.,  Inc. the  placement  agent fees set forth in the

supplement.

     We expect the total offering expenses,  excluding  placement agent fees, to

                           FORWARD LOOKING STATEMENTS

         This prospectus supplement and the accompanying  prospectus contains or
incorporates by reference certain forward-looking  statements within the meaning
of Section 27A of the Securities Act and Section 21E of the Securities  Exchange
Act,  including those identified by the words "believes",  "expects" and similar
expressions.  These forward-looking statements include, among others, statements
related to changes  in market  demand,  competitive  market  conditions,  market
acceptance  of  existing or new  products,  especially  in our Mobile  Solutions
business, guidance related to our future financial performance,  fluctuations in
foreign currency  exchange rates,  the cost and availability of components,  our
ability to manufacture and ship products, the mix of our customer base and sales
channels,  the mix of  products  sold,  our  ability  to  expand  our  sales and
marketing  organization  effectively,  our  ability  to  attract  and retain key
technical and  managerial  employees,  the timing of shipments of products under
contracts and sale of licensing  rights,  development of new products,  disputes
related to our business, inventory,  successful integration of acquisitions, the
seasonality  of  some of our  customers'  demand  and  general  global  economic
conditions.

         These  statements  are  subject to risks and  uncertainties,  including
those set forth in the Risk Factors section in both this  prospectus  supplement
and the  prospectus,  and actual  results  could  differ  materially  from those
expressed or implied in these statements. For example, the overall health of the
economy and the uncertainty  over the war with Iraq and post-war Iraq may result
in  reduced  capital  spending,  which  could  impair  our  ability to reach the
forecasted  growth in GPS  component  technologies  and GPS survey  and  machine
control  products.  Whether we achieve our  guidance  will depend on a number of
factors,  including the continued  uncertain  economic  climate,  as well as the
other risks  detailed  under the heading  "Risk  Factors."  All  forward-looking
statements included in this prospectus are made as of the date hereof. We assume
no obligation to update any such forward-looking  statement or reason why actual
results might differ except as required by the Securities  Exchange Act of 1934,
as  amended.  You  should  not place  undue  reliance  on these  forward-looking
statements.






                          PROSPECTUS SUPPLEMENT SUMMARY

     This  summary  provides an overview  of  selected  information  and may not
contain all of the  information  that is  important  to you. You should read the
entire  prospectus   supplement  and  the  accompanying   prospectus  carefully,
including  the  financial  data,  related  notes  and  the  information  we have
incorporated by reference before making an investment decision.

     Unless otherwise  indicated or unless the context otherwise  requires,  all
references in this  prospectus  supplement to "we," "us," or similar  references
mean Trimble Navigation Limited and its subsidiaries.

     Trimble  Navigation  Limited  provides  advanced  positioning  products and
solutions to industrial,  commercial,  governmental  entities,  and professional
customers   in  a  number  of  markets,   including   surveying,   construction,
agriculture,  urban  and  resource  management,  military,  transportation,  and
telecommunications.  Customer  benefits  resulting  from our products  typically
include cost savings or avoidance,  improved quality,  higher productivity,  and
increased  efficiency.  Examples of our products and solutions  include guidance
for earthmoving  operations,  surveying  instrumentation,  fleet  management for
specialized trucks such as concrete mixers,  positioning  technology for vehicle
navigation and telematics  products,  tractor  guidance for farming,  field data
collection  equipment,  and timing  technology for  synchronization  of wireless
networks.

     Our expertise is focused in  positioning,  communication,  and  information
technologies, which form the core of our products. Positioning technologies used
include the Global Positioning System (GPS), laser, optical, and inertial, while
communication  techniques  include both public  networks  such as cellular,  and
private  networks such as business band radio.  The unique nature of many of our
products  and  solutions  is created  through  information  technologies  - both
firmware that enables the positioning  solution and  applications  software that
allows the customer to make use of the positioning information.

     We design and market our own products.  Assembly and manufacturing for many
of our  products are  subcontracted  to third  parties.  We conduct our business
globally  with major  operations  in the United  States,  Sweden,  Germany,  New
Zealand,   and   the   Netherlands.   Products   are   sold   through   dealers,
representatives, partners, and other channels throughout the world. Products are
supported by sales offices in 22 countries.

     We are organized into four main operating segments encompassing our various
applications and product lines:  Engineering and Construction,  Field Solutions,
Component  Technologies,  and  Mobile  Solutions.  We also  operate  in  smaller
business areas, primarily Military and Advanced Systems.

     We began  operations in 1978 and  incorporated  in California in 1981.  Our
principal  executive  offices are located at 645 North Mary  Avenue,  Sunnyvale,
California 94088. Our telephone number is (408) 481-8000.

                                  growth of our business and do not anticipate
                                  any cash dividends on our common stock in the
                                  foreseeable future.  We are currently

                                  terms of our credit facilities.

                                  RISK FACTORS

         The  common  stock  that is  offered  with this  prospectus  supplement
involves a high degree of risk. You should  carefully  consider the risk factors
in the accompanying  prospectus and in this prospectus supplement in addition to
other information in the accompanying  prospectus and this prospectus supplement
before  deciding to purchase the common stock.  If any of the following risks or
the  risks  in  the  accompanying  prospectus  actually  occurs,  our  business,
financial  condition or results of operations  could be materially and adversely
affected. In this case, the trading price of our common stock could decline, and
you could lose all or part of your investment.

         This  prospectus  supplement also contains  forward-looking  statements
that involve risks and uncertainties. Our actual results could differ materially
from  those  anticipated  in these  forward-looking  statements  as a result  of
certain  factors,  including the risks faced by us described in the accompanying
prospectus and elsewhere in this prospectus supplement.

We are subject to  environmental  laws and potential  exposure to  environmental
liabilities.

         We are subject to various federal,  state and local  environmental laws
and regulations that govern our operations,  including the handling and disposal
of  non-hazardous  and hazardous  wastes,  and emissions and discharges into the
environment.  Failure to comply with such laws and  regulations  could result in
costs for corrective  action,  penalties or the imposition of other liabilities.
We also are subject to laws and regulations  that impose  liability and clean-up
responsibility for releases of hazardous substances into the environment.  Under
certain of these laws and  regulations,  a current or previous owner or operator
of property may be liable for the costs of remediating  hazardous  substances or
petroleum products on or from its property,  without regard to whether the owner
or operator knew of, or caused, the contamination, as well as incur liability to
third  parties  impacted by such  contamination.  The presence of, or failure to
remediate  properly,  such substances  could adversely  affect the value and the
ability to transfer or encumber  such  property.  Based on  currently  available
information,   although  there  can  be  no  assurance,  we  believe  that  such
liabilities will not have a material impact on our business.

We are dependent on proprietary technology.

         Our future  success  and  competitive  position is  dependent  upon our
proprietary  technology,  and we rely on patent,  trade  secret,  trademark  and
copyright  law to  protect  our  intellectual  property.  The  patents  owned or
licensed  by us may be  invalidated,  circumvented  and  challenged.  The rights
granted under these patents may not provide competitive advantages to us. Any of
our pending or future patent  applications may not be issued within the scope of
the claims sought by us, if at all.

         Others may  develop  technologies  that are  similar or superior to our
technology,  duplicate our  technology or design around the patents owned by us.
In addition,  effective  copyright,  patent and trade secret  protection  may be
unavailable,  limited or not applied for in certain foreign countries. The steps
taken by us to protect our technology might not prevent the  misappropriation of
such technology.

         The  value  of our  products  relies  substantially  on  our  technical
innovation  in  fields  in which  there  are many  current  patent  filings.  We
recognize  that as new patents are issued or are brought to our attention by the
holders of such patents or as other  intellectual  property  claims are made, it
may be necessary  for us to withdraw  products  from the market,  take a license
from such patent holders, or redesign our products. We do not believe any of our
products  currently  infringe  patents  or  other  proprietary  rights  of third
parties,  but we cannot be  certain  they do not do so. In  addition,  the legal
costs and  engineering  time required to safeguard  intellectual  property or to
defend against litigation could become a significant expense of operations. Such
events could have a material adverse effect on our revenues or profitability.

We are a party to certain  litigation  matters from time to time in the ordinary
course of our business.

         We are a party to certain  litigation  matters from time to time in the
ordinary course of our business.  For example,  in March of 2000,  Gravquick A/S
filed a lawsuit  against us in the United States District Court for the Northern
District of California.  In this lawsuit,  Gravquick  alleged that we wrongfully
terminated  a European  distribution  agreement  that we had  entered  into with
Gravquick in  violation of the  California  Equipment  Dealers Act.  Although we
obtained a summary judgment order dismissing Gravquick's claims in this lawsuit,



Gravquick  appealed that ruling.  On March 31, 2003,  the United States Court of
Appeals for the Ninth Circuit  overruled  the trial court's  ruling and remanded
the matter to the trial court for further proceedings. If we are found liable to
Gravquick we could be required to pay significant  damages,  including  punitive
damages and attorneys' fees.

Provisions in our charter  documents and under  California  law could prevent or
delay a change of  control,  which could  reduce the market  price of our common
stock.

         Certain  provisions  of our articles of  incorporation,  as amended and
restated,  our  bylaws,  as amended and  restated,  and the  California  General
Corporation  Law may be  deemed  to  have  an  anti-takeover  effect  and  could
discourage a third party from  acquiring,  or make it more difficult for a third
party to  acquire,  control of us without  approval  of our board of  directors.
These  provisions  could also limit the price that  certain  investors  might be
willing to pay in the future for shares of our common stock.  Certain provisions
allow the board of directors to authorize  the issuance of preferred  stock with
rights superior to those of the common stock.

         We have adopted a Preferred Shares Rights Agreement,  commonly known as
a "poison pill". The provisions  described above, our poison pill and provisions
of the California  General  Corporation Law may  discourage,  delay or prevent a
third party from acquiring us.

                                 USE OF PROCEEDS

         We  estimate   that  the  net  proceeds   from  the  offering  will  be
approximately  $36.6  million,  assuming  we sell the  maximum  number of shares
offered  hereby.  Because  there is no minimum  offering  amount  required  as a
condition to closing this offering, the actual public offering amount, placement
fees and proceeds to Trimble, if any, are not presently  determinable and may be
substantially  less than the maximum  amount set forth above.  "Net proceeds" is
what we expect to  receive  based on the  negotiated  public  offering  price of
$18.25  per  share  and  after we pay the  estimated  placement  fees and  other
estimated expenses for this offering.

         We intend to use the entire net  proceeds  of this  offering  to retire
accrued interest and principal under our subordinated note with  Spectra-Physics
Holdings,  Inc. This  subordinated  note, which had an outstanding  principal of
$69,136,000  and  accrued  interest of $5.8  million as of April 8, 2003,  bears
interest at a rate of 10.4% per year and will mature on July 14, 2004.





                              PLAN OF DISTRIBUTION

     We are  selling  the  shares of common  stock  through a  placement  agent.
Subject to the terms and conditions contained in the placement agency agreement,
dated April 8, 2003, Gerard Klauer Mattison & Co., Inc. has agreed to act as the
placement  agent for up to 2,100,000  shares of our common stock.  The placement
agent is not  purchasing  or selling  any shares  hereby,  nor is it required to
arrange the purchase or sale of any specific  number or dollar  amount of common
shares,  but has agreed to use its best  efforts to arrange  for the sale of all
2,100,000 shares.

     The  placement  agency  agreement  provides  that  the  obligations  of the
placement  agent are  subject to certain  conditions  precedent,  including  the
absence of any  material  adverse  change in our  business  and the  receipts of
certain certificates, opinions and letters from us and our counsel.

     The  placement  agent  proposes  to  arrange  for  the  sale to one or more
purchasers  of the shares of common stock  offered  pursuant to this  prospectus
supplement and the accompanying  prospectus  through a direct purchase agreement
between the  purchaser or purchasers  and us. We will pay the placement  agent a
commission  equal to 3.5% of the gross  proceeds of the sale of shares of common
stock.

     The following  table shows the per share and total  commissions we will pay
to the  placement  agent  in  connection  with the  sale of the  shares  offered
pursuant to this prospectus supplement and the accompanying prospectus, assuming
the purchase of all of the shares offered hereby.

Per share.................................................... $0.63875
Maximum offering total....................................... $1,341,375

     Because  there is no minimum  offering  amount  required as a condition  to
closing in this offering, the actual total offering commissions, if any, are not
presently determinable and may be substantially less than the maximum amount set
forth above.

     It is expected  that the sale of up to  2,100,000  shares  pursuant to this
offering  will be completed on April 14, 2003,  if at all. We estimate the total
expenses  of  this  offering  which  will  be  payable  by  us,   excluding  the
commissions, will be approximately $350,000.

     We  have  agreed  to  indemnify   the  placement   agent  against   certain
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to  contribute  to payments  the  placement  agent may be required to make in
respect thereof.

     The placement  agent may, but is not obligated to, engage in passive market
making in  accordance  with  Regulation M under the  Securities  Exchange Act of
1934. In passive market making,  market makers in the common stock,  such as the
placement agent, may, subject to certain limitations, make bids for or purchases
of our common stock.  These transactions may cause the price of the common stock
to be higher than it would  otherwise  be in the absence of these  transactions.
These  transactions  may be effected on the Nasdaq  National Market or otherwise
and, if commenced, may be discontinued at any time.



                                  LEGAL MATTERS

         The validity of the common stock  offered  pursuant to this  prospectus
will be passed  upon by Skadden,  Arps,  Slate,  Meagher & Flom LLP,  Palo Alto,
California,  counsel to Trimble Navigation Limited. Morrison & Foerster LLP, New
York, New York, is acting as counsel for the placement  agent in connection with
selected  legal  matters  relating to the shares of common stock offered by this
prospectus supplement.

                                     SUMMARY

         Trimble Navigation Limited, a California corporation, provides advanced
positioning  products and  solutions  to  industrial,  commercial,  governmental
entities,  and  professional  customers  in  a  number  of  markets,   including
surveying,  construction,  agriculture, urban and resource management, military,
transportation,  and  telecommunications.  Customer benefits  resulting from our
products typically include cost savings or avoidance,  improved quality,  higher
productivity,  and increased efficiency.  Examples of our products and solutions
include guidance for earthmoving operations,  surveying  instrumentation,  fleet
management  for  specialized   trucks  such  as  concrete  mixers,   positioning
technology for vehicle navigation and telematics products,  tractor guidance for
farming,   field  data   collection   equipment,   and  timing   technology  for
synchronization of wireless networks.

         Our expertise is focused in positioning, communication, and information
technologies, which form the core of our products. Positioning technologies used
include the Global Positioning System (GPS), laser, optical, and inertial, while
communication  techniques  include both public networks,  such as cellular,  and
private networks,  such as business band radio. The unique nature of many of our
products  and  solutions  is created  through  information  technologies  - both
firmware that enables the positioning  solution,  and applications software that
allows the customer to make use of the positioning information.

         We design and market our own products.  Assembly and  manufacturing for
many of our products are subcontracted to third parties. We conduct our business
globally,  with major  operations in the United  States,  Sweden,  Germany,  New
Zealand and the Netherlands. Products are sold through dealers, representatives,
partners,  and other channels  throughout  the world.  Products are supported by
sales offices in 22 countries.

         A major  portion  of our  revenues  is  derived  from  applying  GPS to
terrestrial  applications.  GPS  is a  system  of  24  orbiting  satellites  and
associated  ground control that is funded and maintained by the U. S. Government
and is  available  worldwide  free of  charge.  GPS  positioning  is  based on a
technique that precisely  measures  distances from four or more satellites.  The
satellites  continuously  transmit precisely timed radio signals using extremely
accurate atomic clocks. A GPS receiver measures distances from the satellites in
view by  determining  the  travel  time of a signal  from the  satellite  to the
receiver,  and then uses those  distances to compute its position.  Under normal
circumstances,  a stand-alone  GPS receiver is able to calculate its position at
any point on earth,  in the  earth's  atmosphere,  or in lower earth  orbit,  to
approximately  10 meters,  24 hours a day. Much better  accuracies  are possible
through  a  technique  called  "differential  GPS." In  addition,  GPS  provides
extremely accurate time measurement.

         The  usefulness of GPS is dependent  upon the locations of the receiver
and the GPS satellites  that are above the horizon at any given time.  Reception
of GPS signals requires line-of-sight  visibility between the satellites and the
receiver,  which can be  blocked  by  buildings,  hills and dense  foliage.  The
receiver must have a line of sight to at least four  satellites to determine its
latitude, longitude, altitude, and time. The accuracy of GPS may also be limited
by distortion of GPS signals from ionospheric and other atmospheric  conditions,
and intentional or inadvertent  signal  interference or Selective  Availability.
Selective  Availability,  which was the largest component of GPS distortion,  is
controlled by the U.S. Department of Defense and was deactivated on May 1, 2000.

         Our GPS  products are based on  proprietary  receiver  technology.  The
convergence of  positioning,  wireless,  and  information  technologies  enables
significant  new value to be added to positioning  systems,  thereby  creating a
more robust solution for the user. In addition,  recent developments in wireless
technology  and  deployments  of wireless  networks have enabled less  expensive
wireless communications.  These developments allow for the efficient transfer of
position data to locations away from the positioning field device,  allowing the
data to be accessed by more users and thereby increasing productivity.

         Our laser and optical products measure  distances and angles accurately
using light.  We generally  use  commercially  available  laser diodes to create
light beams for distance  measurement.  In addition,  our proprietary  precision
mechanics  and software  algorithms  in these  products  combine to give robust,
accurate  distance  and  angle  measurements  for  a  variety  of  agricultural,
surveying, and construction applications.

         We began  operations in 1978, and  incorporated  in California in 1981.
Our common stock has been publicly traded on Nasdaq since 1990, under the symbol
TRMB.  As used in this  prospectus,  the words "we," "us," "our," and  "Trimble"
refer  to  Trimble  Navigation  Limited,  a  California  corporation,   and  its
wholly-owned subsidiaries.





                                  RISK FACTORS

         You should carefully  consider the following risk factors,  in addition
to the other information contained in this prospectus and in any other documents
to which we refer you in this prospectus,  before purchasing our securities. The
risks and uncertainties described below are not the only ones we face.

Our Inability to Accurately Predict Orders and Shipments May Affect Our Revenue,
Expenses and Earnings per Share.

         We have not  been  able in the past to  consistently  predict  when our
customers  will place  orders and request  shipments,  so that we cannot  always
accurately  plan our  manufacturing  requirements.  As a result,  if orders  and
shipments  differ from what we predict,  we may incur  additional  expenses  and
build excess inventory,  which may require additional accruals.  Any significant
change in our  customers'  purchasing  patterns  could have a  material  adverse
effect on our operating results and reported earnings per share for a particular
quarter.


Our  Operating  Results in Each  Quarter May Be Affected by Special  Conditions,
Such As Seasonality, Late Quarter Purchases, and Other Potential Issues.

         Due, in part, to the buying  patterns of our  customers,  a significant
portion of our quarterly  revenues  occurs from orders  received and immediately
shipped to  customers in the last few weeks and days of each  quarter,  although
our  operating  expenses  tend to remain  fairly  predictable.  Engineering  and
construction  purchases tend to occur in early spring, and governmental agencies
tend to utilize funds available at the end of the  government's  fiscal year for
additional purchases at the end of our third fiscal quarter in September of each
year.  Concentrations of orders sometimes also occur at the end of our other two
fiscal quarters. Additionally, a majority of our sales force earn commissions on
a quarterly basis,  which may cause  concentrations  of orders at the end of any
fiscal quarter.  If for any reason  expected sales are deferred,  orders are not
received,  or  shipments  are  delayed a few days at the end of a  quarter,  our
operating  results and reported  earnings  per share for that  quarter  could be
significantly impacted.


We Are Dependent on a Sole  Manufacturer  and Assembler for Many of Our Products
and on Sole Suppliers of Critical Parts for Our Products.

         Since August 1999, we have been substantially  dependent upon Solectron
Corporation as the exclusive  manufacturing partner for many of our GPS products
previously  manufactured  out of our Sunnyvale  facilities.  Under the agreement
with  Solectron,  we provide to Solectron a  twelve-month  product  forecast and
place  purchase  orders with  Solectron  sixty  calendar  days in advance of the
scheduled delivery of products to our customers. Although purchase orders placed
with Solectron are  cancelable,  the terms of the agreement  would require us to
purchase from Solectron all material inventory not returnable or usable by other
Solectron  customers.  Accordingly,  if we inaccurately  forecast demand for our
products,  we may be unable  to  obtain  adequate  manufacturing  capacity  from
Solectron to meet customers'  delivery  requirements or we may accumulate excess
inventories, if such inventories are not usable by other Solectron customers.

         Our current contract with Solectron expires in August of 2003.

         During the fourth quarter of 2002,  Solectron began  assembling some of
our  Component  Technology  products  in China.  Although  we believe  that this
initiative  in China will bring  significant  cost  savings,  we cannot  predict
potential effects that may result from this program.

          In addition,  we rely on sole  suppliers  for a number of our critical
components.  We have  experienced  shortages of  components  in the past.  As an
example,  we were  affected by the  inability  of a display  supplier to provide
adequate  quantities  to meet our  requirements  in the  third  fiscal  calendar
quarter of 2002 that resulted in the deferral of $2.4 million in orders into the
fourth  quarter of 2002.  Our  current  reliance  on sole or a limited  group of
suppliers involves several risks,  including a potential  inability to obtain an
adequate  supply of required  components and reduced  control over pricing.  Any
inability to obtain  adequate  deliveries or any other  circumstance  that would
require  us to  seek  alternative  sources  of  supply  or to  manufacture  such
components  internally  could  significantly  delay  our  ability  to



ship our products, which could damage relationships with current and prospective
customers and could harm our reputation  and brand,  which could have a material
adverse effect on our business.


Our Annual and Quarterly Performance May Fluctuate.

         Our operating  results have  fluctuated and can be expected to continue
to  fluctuate  in the future on a  quarterly  and annual  basis as a result of a
number of factors,  many of which are beyond our control.  Results in any period
could be affected by:

     o    changes in market demand,

     o    competitive market conditions,

     o    market  acceptance  of existing  or new  products,  especially  in our
          Mobile Solutions business

     o    fluctuations in foreign currency exchange rates,

     o    the cost and availability of components,

     o    our ability to manufacture and ship products,

     o    the mix of our customer base and sales channels,

     o    the mix of products sold,

     o    our   ability   to  expand  our  sales  and   marketing   organization
          effectively,

     o    our  ability  to  attract  and retain  key  technical  and  managerial
          employees,

     o    the  timing of  shipments  of  products  under  contracts  and sale of
          licensing rights, and

     o    general global economic conditions.


         In  addition,  demand for our  products in any quarter or year may vary
due to the seasonal  buying  patterns of our customers in the  agricultural  and
engineering  and  construction  industries.  Due to the foregoing  factors,  our
operating  results in one or more future  periods are  expected to be subject to
significant   fluctuations.   The  price  of  our  common  stock  could  decline
substantially in the event such fluctuations result in our financial performance
being below the expectations of public market analysts and investors,  which are
based  primarily  on  historical  models  that  are  not  necessarily   accurate
representations of the future.


Our Gross Margin Is Subject to Fluctuation.

         Our gross margin is affected by a number of factors,  including product
mix, product pricing,  cost of components,  foreign currency  exchange rates and
manufacturing  costs. For example,  since our Engineering and Construction (E&C)
and Geographic  Information  Systems (GIS) products  generally have higher gross
margins than our Component Technologies products,  absent other factors, a shift
in sales toward E&C and GIS products  would lead to a gross margin  improvement.
On the other hand, if market  conditions in the highly  competitive  E&C and GIS
market  segments  forced us to lower unit  prices,  we would suffer a decline in
gross  margin  unless we were able to timely  offset  the price  reduction  by a
reduction in  production  costs or by sales of other  products with higher gross
margins. A decline in gross margin could have negatively impact our earnings per
share.



Our  Business  is  Subject to  Disruptions  and  Uncertainties  Caused by War or
Terrorism.

         Acts of war or acts of terrorism  could have a material  adverse impact
on our  business,  operating  results,  and financial  condition.  The threat of
terrorism and war and heightened  security and military response to this threat,
or any future acts of terrorism, may cause further disruption to our economy and
create  further   uncertainties.   To  the  extent  that  such   disruptions  or
uncertainties result in delays or cancellations of orders, or the manufacture or
shipment  of our  products,  our  business,  operating  results,  and  financial
condition could be materially and adversely affected.



Our  Substantial  Indebtedness  Could  Materially  Restrict Our  Operations  and
Adversely Affect Our Financial Condition.

         We now  have,  and  for  the  foreseeable  future  expect  to  have,  a
significant level of indebtedness. Our substantial indebtedness could:

     -    increase our  vulnerability  to general adverse  economic and industry
          conditions;

     -    limit  our   ability  to  fund   future   working   capital,   capital
          expenditures,  research and  development  and other general  corporate
          requirements, or to make certain investments that could benefit us;

     -    require  us to  dedicate  a  substantial  portion  of our cash flow to
          service  interest  and  principal  payments  on our debt;  - limit our
          flexibility  to react to changes in our  business  and the industry in
          which we operate; and - limit our ability to borrow additional funds.

Our Credit Agreement Contains Stringent Financial Covenants.

         Two of the financial covenants in our Credit Agreement with The Bank of
Nova Scotia and certain  other banks,  dated as of July 14, 2000 as amended (the
"Credit  Agreement"),  minimum fixed charge coverage and maximum leverage ratio,
are  extremely  sensitive  to  changes  in  earnings  before  interest,   taxes,
depreciation and amortization  ("EBITDA").  In turn, EBITDA is highly correlated
to revenues and costs. Due to uncertainties  associated with the downturn in the
worldwide economy, our future revenues by quarter are more difficult to forecast
and  we  have  put  in  place  various  cost  cutting  measures,  including  the
consolidation  of service  functions  and  centers,  offices,  and of  redundant
product lines and  reductions in staff.  If revenues  should decline at a faster
pace than the rate of these cost cutting measures, on a quarter-to-quarter basis
we may not be in compliance with the two above-mentioned financial covenants. If
we default on one or more  covenants,  we will have to obtain either  negotiated
waivers or amendments to the Credit Agreement.  If we were unable to obtain such
waivers or amendments,  the banks would have the right to accelerate the payment
of our outstanding  obligations under the Credit  Agreement,  which would have a
material adverse effect on our financial condition and viability as an operating
company.  In  addition,  a default  under one of our debt  instruments  may also
trigger  cross-defaults  under our other debt  instruments.  An event of default
under any debt instrument, if not cured or waived, could have a material adverse
effect on us.  In  September  of 2002,  we  reached  an  agreement,  to ease our
financial  covenants.  These revised covenants will remain in effect through the
term of the current credit  facility.  On January 14, 2003,  Trimble executed an
Amended and  Restated  Credit  Agreement,  which  restructured  the $100 million
revolver into four Tranches.  Tranches A & C belong to the $50 million US dollar
revolver and Tranches B & D belong to the $50 million  multi-currency  revolver.
Allocated to Tranche A is $12,500,000  with an expiration  date of July 14, 2003
and allocated to Tranche C is $37,500,000  with an expiration  date of April 07,
2004.  Allocated to Tranche B is $1,500,000  with an expiration date of July 14,
2003 and allocated to Tranche D is $48,500,000  with an expiration date of April
07, 2004. As a result,  the $100 million  revolver will remain in effect through
July 14,  2003 and be reduced to $86 million  for the period  starting  July 15,
2003 through April 7, 2004.

We Are Dependent on Key Customers.

         An increasing  amount of our revenue is generated  from large  original
equipment  manufacturers  such as Siemens VDO Automotive  AG, Nortel,  McNeilus,
Caterpillar,  CNH Global,  DeWalt, Hilti, and Blaupunkt.  A reduction or loss of
business  with  these  customers  could have a  material  adverse  effect on our
financial condition and results of operations. There can be no assurance that we
will be able to  continue  to  realize  value from  these  relationships  in the
future.



We Are Dependent on New Products.

         Our future  revenue  stream depends to a large degree on our ability to
bring new  products  to  market  on a timely  basis.  We must  continue  to make
significant  investments  in research  and  development  in order to continue to
develop new products, enhance existing products and achieve market acceptance of
such products. We may incur problems in the future in innovating and introducing
new products.  Our development stage products may not be successfully  completed
or, if developed,  may not achieve significant customer  acceptance.  If we were
unable to successfully define,  develop and introduce  competitive new products,
and  enhance  existing  products,  our  future  results of  operations  would be
adversely  affected.  Development  and  manufacturing  schedules for  technology
products  are  difficult  to predict,  and we might not achieve  timely  initial
customer shipments of new products. The timely availability of these products in
volume and their acceptance by customers are important to our future success.  A
delay in new  product  introductions  could  have a  significant  impact  on our
results of operations.

We Face Risks of Entering Into and Maintaining Alliances.

         We believe that in certain  emerging markets our success will depend on
our ability to form and maintain alliances with established system providers and
industry  leaders.  Our  failure to form and  maintain  such  alliances,  or the
preemption  of  such  alliances  by  actions  of  other  competitors  or us will
adversely affect our ability to penetrate emerging markets. No assurances can be
given that we will not experience  problems from current or future  alliances or
that we will realize value from any such strategic alliances.


We Are  Dependent  on the  Availability  of  Allocated  Bands  Within  the Radio
Frequency Spectrum.

         Our GPS technology is dependent on the use of the Standard  Positioning
Service ("SPS")  provided by the U.S.  Government's  Global  Positioning  System
(GPS). The GPS SPS operates in radio frequency bands that are globally allocated
for radio  navigation  satellite  services.  International  allocations of radio
frequency  are  made by the  International  Telecommunications  Union  (ITU),  a
specialized  technical  agency of the  United  Nations.  These  allocations  are
further  governed by radio  regulations that have treaty status and which may be
subject  to   modification   every  two  to  three  years  by  the  World  Radio
Communication Conference.

         Any ITU reallocation of radio frequency bands, including frequency band
segmentation  or sharing of spectrum,  may materially  and adversely  affect the
utility and reliability of our products,  which would, in turn, cause a material
adverse  effect on our operating  results.  Many of our products use other radio
frequency  bands,  together  with  the  GPS  signal,  to  provide  enhanced  GPS
capabilities,   such  as  real-time   kinematics   precision.   The   continuing
availability of these non-GPS radio frequencies is essential to provide enhanced
GPS products to our precision survey markets. Any regulatory changes in spectrum
allocation or in allowable  operating  conditions  may  materially and adversely
affect the utility and reliability of our products,  which would, in turn, cause
a material adverse effect on our operating results.

         In addition,  unwanted  emissions  from mobile  satellite  services and
other equipment  operating in adjacent  frequency bands or in-band from licensed
and  unlicensed  devices may  materially  and  adversely  affect the utility and
reliability of our products,  which could result in a material adverse effect on
our  operating  results.  The  FCC  continually  receives  proposals  for  novel
technologies and services, such as ultra-wideband  technologies,  which may seek
to operate in, or across,  the radio  frequency  bands currently used by the GPS
SPS and other public safety services.  Adverse  decisions by the FCC that result
in harmful interference to the delivery of the GPS SPS and other radio frequency
spectrum  also used in our  products may  materially  and  adversely  affect the
utility  and  reliability  of our  products,  which  could  result in a material
adverse effect on our business and financial condition.


We Are Subject to the Adverse Impact of Radio Frequency Congestion.

         We have certain real-time kinematics products,  such as our Land Survey
5700, that use integrated  radio  communication  technology  requiring access to
available radio frequencies  allocated by the FCC. In addition,  access to these
frequencies by state agencies is under management by state radio  communications
coordinators.  Some  bands  are  experiencing  congestion  that  excludes  their
availability for access by state agencies in some states, including the state



of California.  An inability to obtain access to these radio  frequencies  could
have an adverse effect on our operating results.


Many of Our Products Rely on the GPS Satellite System.

         The GPS  satellites  and  their  ground  support  systems  are  complex
electronic  systems  subject to electronic and mechanical  failures and possible
sabotage. The satellites were originally designed to have lives of 7.5 years and
are subject to damage by the hostile  space  environment  in which they operate.
However,  of the current deployment of 28 satellites in place, some have already
been in operation for 13 years. To repair damaged or  malfunctioning  satellites
is currently not economically  feasible.  If a significant  number of satellites
were to become  inoperable,  there could be a substantial  delay before they are
replaced with new satellites.  A reduction in the number of operating satellites
may impair the  current  utility of the GPS system and the growth of current and
additional market opportunities.

         In addition,  there can be no assurance that the U.S.  Government  will
remain  committed to the operation and maintenance of GPS satellites over a long
period,  or that the policies of the U.S.  Government for the use of GPS without
charge will remain unchanged.  However,  a 1996 Presidential  Decision Directive
marks the first time in the  evolution  of GPS that access for civilian use free
of direct user fees is  specifically  recognized  and supported by  Presidential
policy. In addition,  Presidential policy has been complemented by corresponding
legislation, signed into law. Because of ever-increasing commercial applications
of GPS, other U.S. Government agencies may become involved in the administration
or the regulation of the use of GPS signals.  Any of the foregoing factors could
affect the  willingness  of buyers of our products to select  GPS-based  systems
instead of products based on competing technologies.

         Any  resulting  change in market  demand for GPS products  could have a
material  adverse  effect  on  our  financial  results.  For  example,  European
governments  have  expressed  interest  in  building  an  independent  satellite
navigation system, known as Galileo. Depending on the as yet undetermined design
and operation of this system,  there may be  interference to the delivery of the
GPS SPS and may materially and adversely  affect the utility and  reliability of
our products,  which could result in a material  adverse  effect on our business
and operating results.

We Face Risks in Investing in and Integrating New Acquisitions.

         We are  continuously  evaluating  external  investments in technologies
related  to our  business,  and have  made  relatively  small  strategic  equity
investments in a number of GPS-related and laser-related  technology  companies.
Acquisitions  of, and  investments,  in companies,  divisions of  companies,  or
products entail numerous risks, including:

     o    potential inability to successfully  integrate acquired operations and
          products or to realize cost savings or other anticipated benefits from
          integration;

     o    diversion of management's attention;

     o    loss of key employees of acquired operations;

     o    the difficulty of assimilating geographically dispersed operations and
          personnel of the acquired companies;

     o    the potential disruption of our ongoing business;

     o    unanticipated expenses related to such integration;

     o    the correct  assessment  of the  relative  percentages  of  in-process
          research and development  expense that can be immediately  written off
          as compared to the amount which must be amortized over the appropriate
          life of the asset;

     o    the impairment of relationships with employees and customers of either
          an acquired company or our own business;



     o    the potential unknown  liabilities  associated with acquired business;
          and

     o    inability  to  recover  strategic  investments  in  development  stage
          entities.

         As a result  of such  acquisitions,  we have  significant  assets  that
include  goodwill  and  other  purchased  intangibles.   The  testing  of  these
intangibles  under  established  accounting  guidelines for impairment  requires
significant  use of judgment  and  assumptions.  Changes in business  conditions
could require adjustments to the valuation of these assets. In addition,  losses
incurred by a company in which we have an investment may have a direct impact on
our financial  statements or could result in our having to write-down  the value
of such investment. Any such problems in integration or adjustments to the value
of the  assets  acquired  could  harm our  growth  strategy  and have a material
adverse effect on our business,  financial  condition and  compliance  with debt
covenants.

We Face Competition in Our Markets.

         Our markets are highly  competitive  and we expect that both direct and
indirect  competition  will  increase  in the future.  Our  overall  competitive
position  depends  on a number of  factors  including  the  price,  quality  and
performance of our products,  the level of customer service,  the development of
new technology and our ability to participate in emerging  markets.  Within each
of our markets,  we encounter  direct  competition  from other GPS,  optical and
laser  suppliers and  competition may intensify from various larger domestic and
international  competitors  and new  market  entrants,  some of which may be our
current customers.  The competition in the future, may, in some cases, result in
price  reductions,  reduced margins or loss of market share,  any of which could
materially and adversely  affect our business,  operating  results and financial
condition.  We believe  that our ability to compete  successfully  in the future
against  existing and additional  competitors will depend largely on our ability
to execute our  strategy  to provide  systems and  products  with  significantly
differentiated  features compared to currently available products. We may not be
able to  implement  this  strategy  successfully,  and our  products  may not be
competitive  with other  technologies  or products  that may be developed by our
competitors,  many of whom  have  significantly  greater  financial,  technical,
manufacturing, marketing, sales and other resources than we do.

We Are Dependent on Proprietary Technology.

         Our future  success  and  competitive  position is  dependent  upon our
proprietary  technology,  and we rely on patent,  trade  secret,  trademark  and
copyright  law to  protect  our  intellectual  property.  The  patents  owned or
licensed by us may not be invalidated,  circumvented and challenged.  The rights
granted under these patents may not provide competitive advantages to us. Any of
our pending or future patent  applications may not be issued within the scope of
the claims sought by us, if at all.

         Others may not develop technologies that are similar or superior to our
technology,  duplicate our  technology or design around the patents owned by us.
In addition,  effective  copyright,  patent and trade secret  protection  may be
unavailable,  limited or not applied for in certain foreign countries. The steps
taken by us to protect our technology might not prevent the  misappropriation of
such technology.

         The  value  of our  products  relies  substantially  on  our  technical
innovation  in  fields  in which  there  are many  current  patent  filings.  We
recognize  that as new patents are issued or are brought to our attention by the
holders of such patents or as other  intellectual  property  claims are made, it
may be necessary  for us to withdraw  products  from the market,  take a license
from such patent holders, or redesign our products. We do not believe any of our
products  currently  infringe  patents  or  other  proprietary  rights  of third
parties,  but we cannot be  certain  they do not do so. In  addition,  the legal
costs and  engineering  time required to safeguard  intellectual  property or to
defend against litigation could become a significant expense of operations. Such
events could have a material adverse effect on our revenues or profitability.

We Must Carefully Manage Our Future Growth.

         Growth  in  our  sales  or  continued  expansion  in the  scope  of our
operations could strain our current  management,  financial,  manufacturing  and
other  resources  and may  require  us to  implement  and  improve a variety  of
operating, financial and other systems, procedures and controls. Specifically we
have  experienced  strain in our financial  and order  management  system,  as a
result  of  our   acquisitions.   We  are  expanding   our  sales,   accounting,
manufacturing,  and other information  systems to meet these  challenges.  These
systems,  procedures  or controls may not be adequate to


support our  operations  and may not be designed,  implemented  or improved in a
cost effective and timely manner.  Any failure to implement,  improve and expand
such systems,  procedures  and controls in a timely and  efficient  manner could
harm our growth  strategy  and  adversely  affect our  financial  condition  and
ability to achieve our business objectives.

We Are Dependent on Retaining and  Attracting  Highly  Skilled  Development  and
Managerial Personnel.

         Our ability to maintain our  competitive  technological  position  will
depend, in a large part, on our ability to attract,  motivate, and retain highly
qualified  development  and  managerial  personnel.  Competition  for  qualified
employees in our industry and location is intense, and there can be no assurance
that we will be able to attract,  motivate and retain enough qualified employees
necessary for the future continued development of our business and products.

We May Encounter Problems Associated With International Operations and Sales.

         Our customers are located  throughout the world.  Sales to unaffiliated
customers in foreign locations represented  approximately 49% of our revenues in
our fiscal  year 2002,  50% in our fiscal  year 2001 and 52% in our fiscal  year
2000.  In addition,  we have  significant  international  operations,  including
manufacturing facilities,  sales personnel and customer support operations.  Our
international sales organization  contains offices in 21 foreign countries.  Our
international  manufacturing facilities are in Sweden and Germany, and we have a
regional  fulfillment  center in the  Netherlands.  Our  international  presence
exposes us to risks not faced by wholly  domestic  companies.  Specifically,  we
have experienced issues relating to integration of foreign  operations,  greater
difficulty in accounts receivable collection, longer payment cycles and currency
fluctuations. Additionally, we face the following risks, among others:

     o    unexpected changes in regulatory requirements;

     o    tariffs and other trade barriers;

     o    political,   legal  and  economic   instability  in  foreign  markets,
          particularly in those markets in which we maintain  manufacturing  and
          research facilities;

     o    difficulties in staffing and management;

     o    language  and  cultural  barriers;  seasonal  reductions  in  business
          activities in the summer months in Europe and some other countries;

     o    war and acts of terrorism; and

     o    potentially adverse tax consequences.

         Although we implemented a program to attempt to manage foreign exchange
risks through hedging and other strategies,  there can be no assurance that this
program will be successful and that currency exchange rate fluctuations will not
have a material  adverse  effect on our results of operations.  In addition,  in
certain foreign markets,  there may be reluctance to purchase  products based on
GPS technology, given the control of GPS by the U.S. Government.

We are exposed to fluctuations in Currency Exchange Rates.

         A significant  portion of our business is conducted  outside the United
States, and as such, we face exposure to adverse movements in non-U.S.  currency
exchange  rates.  These  exposures  may change over time as  business  practices
evolve and could have a material  adverse  impact on our  financial  results and
cash flows.  Compared  to fiscal  2001,  in fiscal  2002,  the US  currency  has
weakened against other currencies.

         Currently,  we hedge  only those  currency  exposures  associated  with
certain  assets and  liabilities  denominated  in  nonfunctional  currencies and
periodically  will hedge  anticipated  foreign  currency cash flows. The hedging
activities  undertaken  by us are  intended  to offset  the  impact of  currency
fluctuations  on certain  nonfunctional  currency  assets and  liabilities.  Our
attempts to hedge  against  these risks may not be  successful  resulting  in an
adverse impact on our net income.



We Are Subject to the Impact of Governmental and Other Similar Certifications.

         We market certain products that are subject to governmental and similar
certifications  before  they can be sold.  For  example,  CE  certification  for
radiated  emissions is required  for most GPS  receiver and data  communications
products sold in the European Union. An inability to obtain such  certifications
in a timely manner could have an adverse effect on our operating results.  Also,
our products  that use  integrated  radio  communication  technology  require an
end-user to obtain  licensing from the Federal  Communications  Commission (FCC)
for  frequency-band  usage.  These are  secondary  licenses  that are subject to
certain  restrictions.  During the fourth quarter of 1998,  the FCC  temporarily
suspended  the  issuance of licenses  for  certain of our  real-time  kinematics
products  because of  interference  with  certain  other users of similar  radio
frequencies.  An inability or delay in obtaining such  certifications or changes
to the rules by the FCC could adversely affect our ability to bring our products
to market,  which  could  harm our  customer  relationships  and have a material
adverse effect on our business.

The volatility of our stock price could adversely  affect your investment in our
common stock.

         The market price of our common stock has been,  and may continue to be,
highly volatile.  During 2002, our stock price ranged from a high of $18.50 to a
low of $8.02.  We believe that a variety of factors could cause the price of our
common stock to fluctuate, perhaps substantially, including:

     -    announcements  and rumors of  developments  related to our business or
          the  industry in which we compete;

     -    quarterly  fluctuations in our actual or anticipated operating results
          and order  levels;

     -    general conditions in the worldwide economy, including fluctuations in
          interest rates;

     -    announcements of technological innovations;

     -    new products or product enhancements by us or our competitors;

     -    developments  in patents  or other  intellectual  property  rights and
          litigation;

     -    developments in our relationships with our customers and suppliers;

     -    any  commencement of armed  hostilities  between the United States and
          Iraq; and

     -    any significant acts of terrorism against the United States.

         In  addition,  in  recent  years the stock  market in  general  and the
markets for shares of  "high-tech"  companies in  particular,  have  experienced
extreme  price  fluctuations  which have often been  unrelated to the  operating
performance of affected  companies.  Any such  fluctuations  in the future could
adversely  affect the market price of our common stock,  and the market price of
our common stock may decline.

                              PLAN OF DISTRIBUTION

         We may sell the securities  being offered  pursuant to this  prospectus
directly to purchasers,  to or through underwriters,  through dealers or agents,
or through a combination of such methods. The prospectus supplement with respect
to the  securities  being  offered  will set forth  the  terms of the  offering,
including the names of the underwriters, dealers or agents, if any, the purchase
price, the net proceeds to Trimble,  any underwriting  discounts and other items
constituting underwriters'  compensation,  and initial public offering price and
any  discounts  or  concessions  allowed or reallowed or paid to dealers and any
securities exchanges on which such securities may be listed.

         If  underwriters   are  used  in  an  offering,   we  will  execute  an
underwriting  agreement with such underwriters and will specify the name of each
underwriter  and  the  terms  of the  transaction  (including  any  underwriting
discounts and other terms constituting  compensation of the underwriters and any
dealers) in a prospectus  supplement.  If an underwriting syndicate is used, the
managing  underwriter(s)  will  be  specified  on the  cover  of the  prospectus
supplement. If underwriters are used in the sale, the offered securities will be
acquired by the  underwriters for their own accounts and may be resold from time
to time in one or more transactions,  including  negotiated  transactions,  at a
fixed public offering price or at varying prices determined at the time of sale.
Any public offering price and any discounts or concessions  allowed or reallowed
or paid to dealers may be changed from time to time.  Unless otherwise set forth
in the prospectus  supplement,  the obligations of the  underwriters to purchase
the  offered  securities  will  be  subject  to  conditions  precedent  and  the
underwriters will be obligated to purchase all of the offered  securities if any
are purchased.

         If dealers are used in an offering,  we will sell the securities to the
dealers as principals.  The dealers then may resell the securities to the public
at varying prices,  which they determine at the time of resale. The names of the
dealers  and the terms of the  transaction  will be  specified  in a  prospectus
supplement.

         The  securities  may  be  sold  directly  by us or  through  agents  we
designate.  If agents are used in an  offering,  the names of the agents and the
terms  of the  agency  will be  specified  in a  prospectus  supplement.  Unless
otherwise  indicated  in a  prospectus  supplement,  the  agents  will  act on a
best-efforts basis for the period of their appointment.

         Dealers and agents named in a prospectus supplement may be deemed to be
underwriters  (within  the  meaning  of  the  Securities  Act  of  1933)  of the
securities  described therein. In addition,  we may sell the securities directly
to institutional investors or others who may be deemed to be underwriters within
the meaning of the Securities Act of 1933 with respect to any resales thereof.

         Underwriters, dealers and agents, may be entitled to indemnification by
us  against  specific  civil  liabilities,   including   liabilities  under  the
Securities  Act of 1933, or to  contribution  with respect to payments which the
underwriters  or  agents  may be  required  to make in  respect  thereof,  under
underwriting or other agreements.  The terms of any  indemnification  provisions
will be set forth in a prospectus supplement.  Certain underwriters,  dealers or
agents  and their  associates  may  engage in  transactions  with,  and  perform
services for us in the ordinary course of business.

         If  so  indicated  in  a  prospectus  supplement,   we  will  authorize
underwriters  or other  persons  acting  as our  agents  to  solicit  offers  by
institutional  investors to purchase  securities pursuant to contracts providing
for  payment  and  delivery  on a  future  date.  We may  enter  contracts  with
commercial and savings banks,  insurance  companies,  pension funds,  investment
companies,  educational  and  charitable  institutions  and other  institutional
investors.  The obligations of any institutional investor will be subject to the
condition that its purchase of the offered  securities  will not be illegal,  at
the time of delivery.  The underwriters and other agents will not be responsible
for the validity or performance of contracts.

         Any common  stock sold  pursuant  to a  prospectus  supplement  will be
eligible  for  quotation  and trading on Nasdaq,  subject to official  notice of
issuance.  Any  underwriters  to whom  securities are sold by Trimble for public
offering  and sale may make a market in the  securities,  but such  underwriters
will not be obligated to do so and may discontinue any market making at any time
without notice.



                             VALIDITY OF SECURITIES

         The validity of the common stock  offered  pursuant to this  prospectus
