SUNNYVALE, Calif., Jan. 20, 2004 -- Trimble (NASDAQ: TRMB) announced today that it has been awarded two contracts from the U.S. Air Force (USAF) to provide Global Positioning System (GPS) surveying and mapping systems. The GPS equipment will be used as part of the GeoBase Civil Engineering Program for worldwide surveying and construction projects. The contracts are valued at approximately $5 million.

Under the contract, Trimble will supply GPS Total Station® 5700 GPS surveying systems, GPS Pathfinder® Pro XRS mapping systems, GeoExplorer® CE series GPS handheld receivers, and training. The systems will be used to collect accurate position data to map USAF Base installation assets as well as build base camps and airfields worldwide. The integration of position data with asset information will assist in managing the USAF Base installation's physical infrastructure. In addition, the systems may be used to assist during natural disasters and with community service projects.

About GeoBase

The GeoBase program represents a major paradigm shift in how geospatial information resources are being acquired, implemented, exploited, and sustained on USAF installations around the world. GeoBase aims to deliver a comprehensive, integrated geospatial information infrastructure supporting "Blue Force" basing requirements. With the vision of "One Installation...One Map", GeoBase will give commanders a decision support tool providing a common, georeferenced view of all their infrastructure assets to answer questions such as-what is it, where is it, and what's around each installation.

5700 RTK GPS Surveying System

The Trimble GPS Total Station 5700 is an easy-to-use modular system. It provides surveyors with total flexibility, using different set-up configurations for all types of surveying tasks. The receiver can be configured with all the components and mounted on a lightweight range pole or worn with a belt pouch. The system can also be mounted on a tripod, vehicle, boat, ATV or placed in a backpack.

The systems include dual-frequency 5700 GPS receivers, ruggedized handheld TSCE™ controllers, Trimble Geomatics Office™ processing software, radios, antennas and accessories which include back packs, tripods, transit cases and batteries. Each system can be deployed as either a precision mobile survey unit or as a reference station to provide Real-Time Kinematic (RTK) data signals to the mobile unit. With the addition of the 5700 RTK systems, the USAF survey equipment now includes GPS, servo and robotic total stations from Trimble.

At the heart of the system is a low-power, GPS receiver, which provides higher speed, longer battery life, better satellite tracking and higher precision in extreme environments. The GPS receiver also includes an internal radio modem and the extended Real-time Kinematic (eRTK™) technology, which can cover areas up to four times larger than conventional RTK.

The 5700 receiver is housed in an extremely rugged, space-age magnesium alloy case which is lighter than aluminum, yet 30% stronger. The receiver weighs less than 1.4kgs. (3 lbs), including batteries for a full day's work, internal radio, radio antenna and internal charger.

In addition, the GPS system works with the Zephyr™ and Zephyr Geodetic™ antennas, both using the patented Trimble 4-point antenna feed technology. The Zephyr Geodetic antenna features the patented Trimble Stealth™ ground plane technology, which mitigates multipath signals.
