               Trimble Reports Record First Fiscal Quarter Results
         Company Reports Revenue and GAAP EPS Ahead of Previous Guidance

SUNNYVALE,  Calif.,  Apr.  29, 2003 - Trimble  (Nasdaq:  TRMB)  today  announced
results for its first fiscal quarter ended April 4, 2003.  The Company  reported
first quarter  revenues of $127.3  million,  versus $104.0  million in the first
quarter of 2002.  Earnings per share (EPS) for the first  quarter on a Generally
Accepted  Accounting  Principles  (GAAP)  basis were  $0.18,  which  included an
expense for approximately  $1.8 million in amortization of intangibles under FAS
142 and an  approximate  $390,000  restructuring  charge  related  to  Trimble's
continued  cost  reduction  activities.  This  compares  to a loss per  share of
($0.03),   which  included  an  expense  for   approximately   $2.0  million  in
amortization  of intangibles  and a $304,000  restructuring  charge in the first
quarter of 2002.  First quarter 2003 GAAP EPS were calculated on a diluted basis
using approximately 30.1 million shares.

"We  continued  to  demonstrate  the  ability to execute in  uncertain  economic
times," said Steven W. Berglund,  president and CEO of Trimble.  "Our survey and
machine control  products bring real  productivity  benefits and cost savings to
our  customers,  which has translated  into increased  sales and profits for the
Company.  Additionally,  our Component Technologies business remains robust with
favorable margin trends, and our Mobile Solutions business demonstrated tangible
progress on both increasing  revenue and decreasing  operating losses during the
quarter."

First Fiscal Quarter Business Segment Highlights
Engineering and Construction (E&C)
Total  first  quarter  E&C  (including  Tripod Data  Systems  (TDS),  previously
included in the Portfolio Technologies segment) revenues increased by 19 percent
on a comparable  basis over the first quarter of 2002. All business areas within
E&C  showed  double-digit  year over  year  growth in the  quarter.  GPS  survey
products had record  sales for the second  consecutive  quarter.  E&C sales also
benefited  from a  positive  reception  to new  products  such  as the  recently
introduced  LM80,  which is a  combination  of the TDS  Recon(TM),  a moderately
priced,  ruggedized  handheld  computer,  and a new  software  package  used  to
increase  productivity,  accuracy and  reliability for the  construction  layout
process.

Trimble Field Solutions (TFS) - Agriculture and Geographic  Information  Systems
(GIS) Trimble Field Solutions' first quarter revenue  increased by approximately
15 percent over the first quarter of 2002.  The GIS and  Agriculture  businesses
each  demonstrated  double-digit  revenue growth over the first quarter of 2002,
with Agriculture  benefiting from seasonal strength due to farmers preparing for
the planting season.

Component Technologies (CT)
CT first quarter  revenues  increased by approximately 58 percent over the first
quarter of 2002.  Demand was strong  across the board,  especially  for wireless
infrastructure  products.  Margins also demonstrated  strong  improvement due to
favorable  product  mix,  increased  volumes,  and cost  reductions  related the
transfer of the  business'  manufacturing  operations  from  California to China
during the second half of 2002.

Trimble Mobile Solutions (TMS)
TMS  reported  a 55 percent  sequential  increase  in  revenue  during the first
quarter,  as it  continued to gain  traction in the ready mix  concrete  market.
Revenue  related to the  Televisant(TM)  Mobile Resource  Management  System and
associated hardware products increased by over 250 percent sequentially, and now
represent a majority of TMS'  business.  At the same time,  divisional  net loss
decreased by approximately 71 percent from the fourth quarter.

Guidance
For the second quarter ending July 4, 2003, the Company expects revenues will be
between   $129.0  and  $132.0   million.   Gross  margins  are  expected  to  be
approximately  50 percent.  Operating  expenses,  including  approximately  $1.8
million of amortization of intangibles are expected to be  approximately  $51 to
$52 million.  Net interest expense is expected to be approximately $2.6 million,
and the income tax provision  should be  approximately  $1 million.  The Company
anticipates other non-operating expense to be approximately $1.5 million. Within
these  revenue  guidelines,  Trimble  expects  GAAP EPS to be between  $0.25 and
$0.29, assuming 32.2 million shares outstanding.

Forward Looking Statement:
Certain  statements  made in this press release are forward  looking  statements
within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the  Securities  Exchange Act of 1934,  as amended,  and are made
pursuant to the safe harbor  provisions of the Securities  Litigation Reform Act
of 1995. These statements include the revenue, gross margin, operating expenses,
net interest expense, non-operating expense and earnings per share estimates for
the quarter ending July 4, 2003. These forward-looking statements are subject to
change,  and actual results may  materially  differ from those set forth in this
press release due to certain risks and uncertainties. For example, the Company's
early success at converting  customers  who have been  piloting  Trimble  Mobile
Solutions  into full fleet  customers may not be predictive of the rates current
customers  in its pilot  program  convert and any  failure to achieve  predicted
results could  negatively  impact the Company's  revenues and gross margin.  The
overall  health of the  economy  and the  uncertainty  over  SARs may  result in
reduced capital  spending which could impair the Company's  ability to reach the
forecasted results. In addition, many of the Company's products are manufactured
in China and those  operations  could be  harmed  by the SARs  outbreak  in that
country.  Whether the Company  achieves its guidance for the second quarter will
also depend on a number of other factors, including the risks detailed from time
to time in reports filed with the SEC,  including its quarterly  reports on Form
10-Q and its annual report on Form 10-K.  Undue reliance should not be placed on
any forward-looking  statement,  contained herein.  These statements reflect the
Company's  position  as of the  date  of this  release.  The  Company  expressly
disclaims any  undertaking  to release  publicly any updates or revisions to any
statements to reflect any change in the Company's  expectations or any change of
events, conditions, or circumstances on which any such statement is based.
