March 22, 2007 -- Trimble (NASDAQ:TRMB) announced today it has been chosen by the Polish National Office of Geodesy and Cartography, GUGiK, to supply 78 Continuous Operating Reference Station (CORS) receivers and Trimble VRS™ (Virtual Reference Station) technology to establish a nationwide Global Satellite Navigation Positioning System (GNSS) infrastructure network for the country of Poland. The Trimble VRS network will provide a geospatial infrastructure for surveying, engineering and Geographic Information System (GIS) professionals that enables high accuracy real-time kinematic (RTK) GNSS positioning without the need of separate base stations or software, significantly increasing efficiency and productivity.

The GNSS network, known as ASG (Aktywna Siec Geodezyjna or Network for Online Positioning User Service), will be operated by GUGiK. It will be the second network in Poland and will supply centimeter-level RTK GNSS data for a variety of positioning applications including geodetic and cadastral surveying, road and bridge construction, scientific research as well as other high-accuracy positioning applications. GUGiK is constructing the network in accordance with the standards of the European geospatial infrastructure initiative EUPOS (European Position Determination System). The ASG is expected to be one of the largest reference station networks in Eastern Europe when operational. In addition to the network CORS receivers and network software, GUGiK has also purchased 65 Trimble R8 RTK rovers for its surveying operations.

With the advantages of Trimble VRS softwares advanced ionospheric and troposheric modeling, the extended inter-station spacing allows for the 78 selected Trimble CORS receivers with Trimble Zephyr™ Geodetic antennas to cover the entire country of Poland. In addition to improving the accuracy of positioning results, the network is expected to enable fast measurements within 2-5 seconds. The use of the network will be free of charge for surveyors for the three years.

The ASG network will provide a highly reliable, cost-effective means for surveyors and other professionals to work faster and achieve more accurate GNSS results. The nationwide network is expected to provide opportunities for the positioning industry that could bring significant business benefits. It will also make it easier to combine GNSS technology with traditional optical surveying methods because the results are available in real-time. In addition, simultaneous use of GNSS and optical equipment does not require complex preparations and data exchange.

The nationwide Polish GNSS network follows more than 80 Trimble infrastructure installations throughout the world including: China, Germany, Austria, Switzerland, U.S., Singapore, Portugal, Canada, Norway, Sweden, Finland, Denmark, Belgium, France, Spain, Italy, United Kingdom, Netherlands, Serbia, Slovenia, Slovakia, New Caledonia, Australia, Malaysia, Taiwan, South Korea, Southern Poland and Japan.

About GUGiK

Established in 1945, the Polish Head Office of Geodesy and Cartography (Glowny Urzad Geodezji I Kartografii or GUGiK) oversees all geodesy and cartography activities in the Republic of Poland. GUGiK performs many functions including establishing and maintaining geodetic and gravimetric networks; preparing official topographic maps; providing a national resource of geodetic and cartographic data as well as a cadastral register of land and buildings.

About Trimble VRS Technology

Trimble VRS technology uses the RTK solutions from Trimble RTKNet™ software and provides high-accuracy, RTK GNSS positioning for wider areas. The VRS network is available at any time without setting up a base station and provides common control anywhere in the network.

Because Trimble RTKNet software is able to process the entire network simultaneously, Trimble VRS networks offer greater quality control and higher data accuracy at longer distances. In the field, the farther users get from a reference station using conventional RTK, the more susceptible they become to reduced accuracy and performance due to systematic errors such as ionospheric and tropospheric effects. In a Trimble VRS network, RTKNet software provides a fully modeled solution that factor in potential systematic errors. Users connect into the system using a wireless connection; the software acknowledges the users field positions and allows them to operate as though there is a reference station—a virtual reference station—right next to their rover. As a result, the PPM error is eliminated or significantly reduced, allowing surveyors to achieve RTK precision over much greater distances with fewer reference stations. Users can also retrieve stored GNSS and modeled data from the control center via the Internet for post-processing.
