Croatia Taps Trimble to Provide a Nationwide GNSS Infrastructure Network

Sunnyvale, Calif., May 29, 2008 — Trimble (NASDAQ:TRMB) announced today it has been chosen by the Central Financing and Contracting Unit (CFCU) at the Croatian Ministry of Finance to supply 31 Trimble® NetR5™ Reference Stations, 31 Trimble Zephyr Geodetic™ antennas and Trimble VRS™ (Virtual Reference Station) technology to establish a nationwide Global Navigation Satellite System (GNSS) infrastructure network for the Republic of Croatia called the CROatian POsitioning System (CROPOS). 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 for separate base stations, significantly increasing efficiency and productivity.

The CROPOS network, the largest and only nation-wide network in the country, will be operated by the State Geodetic Administration of the Republic of Croatia – Državna Geodetska Uprava (DGU). The turn-key VRS solution by Trimble includes installation of the control center as well as third-party components including communications and IT devices. In addition, Trimble is also providing Trimble R8 GNSS rover systems for survey and control work.

Croatia plans to use CROPOS as the basis for the country’s new geodetic reference coordinate system. The VRS network will provide a highly reliable, cost-effective means for surveyors and other geospatial professionals to work faster and achieve accurate GNSS results for a variety of positioning applications including geodetic and cadastral surveying, road and bridge construction, earthquake and tectonic plate movement monitoring and analysis, and scientific research, as well as other high-accuracy positioning applications.

The Croatia network follows more than 200 Trimble infrastructure installations throughout the world including: Australia, Austria, Belgium, Brazil, Brunei, Canada, China, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, India, Ireland, Italy, Japan, Lithuania, Malaysia, Netherlands, New Caledonia, New Zealand, Norway, Poland, Portugal, Republic of South Africa, Russia, Saudi Arabia, Serbia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, the United Kingdom and U.S. For a partial reference list of Trimble VRS installations visit:

About Trimble VRS Technology
Trimble VRS technology uses Trimble RTKNet™ software and provides high-accuracy, RTK GNSS positioning for wider areas. The VRS network can be continuously available 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 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.
