LE34 Establishes Infrastructure in Denmark with Trimble GPS

Trimble GPS and Virtual Reference Station Software to Offer Reliable, High-Precision Services for GPS Users


SUNNYVALE, Calif., Oct. 24, 2001 - Trimble (NASDAQ:TRMB) announced today it has supplied Global Positioning System (GPS) reference stations and Virtual Reference Station (VRS) software to LE34 Tele A/S to establish GPSnet.dk, which provides networked real-time kinematic (RTK) services across Denmark. The core infrastructure service is monitored and operated by LE34. GPS users throughout Denmark can utilize the services for surveying, construction, navigation, asset management, agriculture and forestry.
 
The establishment of GPSnet.dk follows other Trimble infrastructure project successes. These include: the Japanese Geographical Survey Institute Nationwide Network, VRS network in Switzerland for the Swiss government, GPS reference stations for the General Lighthouse Authority Network around the coast of Great Britain, the Channel Tunnel Rail Link RTK Network, and the Zurich International Airport Expansion Project.
 
About GPSnet.dk
 
The GPS network, called GPSnet.dk consists of 26 Trimble GPS reference stations, Trimble GPSNetTM, RTKNetTM, Webserver software and a communications infrastructure. Installation of the Reference Stations was completed early in 2001 and the service is now operational and available to subscribers.
 
The software links the GPS reference stations and enables centimeter-level positioning without the need to set up a local reference station. Users can achieve long-range RTK precision over greater distances via wireless communications in the field. Trimble Terrasat developed the VRS software suite.
 
The VRS software consists of a network of Trimble GPS receivers communicating with a control center to calculate GPS error corrections that are applicable over a wide area. These error corrections are transmitted via GSM cellar telephones to users in the field within the network area. Additionally, users can retrieve stored GPS correction data from the control center via the Internet for post-processing.
 
VRS technology overcomes previous limitations with high precision GPS. The system significantly reduces systematic errors in the reference station data to improve reliability and operating range. This allows a user to increase the distance at which the rover receiver is located from the physical reference stations while improving on-the-fly (OTF) initialization times. Traditionally, for precise GPS applications-surveying, construction, precision farming and high accuracy Geographic Information System (GIS)-roving receivers required a reference station within 10 kilometers to ensure centimeter level accuracy. With VRS, users within the reference station network can operate consistently at greater distances without degrading accuracy.
