Trimble GNSS Solution Optimizes Positioning Performance
Known as AGNES (Automated GPS Network for Switzerland), the Swiss infrastructure enables swisstopo to provide the Swiss Positioning Service (swipos), which supplies RTK GPS and Differential Global Positioning System (DGPS) corrections to users of the network. By implementing Trimble NetR5 GNSS reference stations, which support the modernized GPS L2C and L5 signals as well as GLONASS L1/L2 signals, the network will be upgraded and called AGNES II. In addition, the selection of the new Trimble Zephyr Geodetic 2 antennas provides AGNES II compatibility with future planned constellations and frequencies.
Originally built in 1999 with Trimble GPS receivers, the network covers the entire 41,000 square kilometers (25, 476 square miles) of Switzerland, which is known for its extreme topography ranging from mountains over 4,000 meters (13,123 feet) high to its lowest lake at 193 meters (633 feet). Users of AGNES II will be able to optimize positioning performance particularly in reception-critical areas, such as areas with interrupted reception and zones with extreme topographic features.
In addition, the use of Trimble RTKNet(TM) software provides AGNES II with Trimble VRS(TM) (Virtual Reference Station) functionality, which computes a virtual reference station for the user in the field, increasing system reliability and allowing significantly greater distances between reference stations. The VRS network will provide a highly reliable, cost-effective means for surveyors and other professionals to work faster and achieve more accurate GNSS results.
The AGNES II network is designed to cover the needs of swisstopo into the future and will enable accurate and reliable centimeter-level surveying measurements to be taken faster and more cost-effectively throughout Switzerland. AGNES II is expected to be fully operational by summer of 2007.
The nationwide Swiss VRS network follows more than 80 Trimble infrastructure installations networks throughout the world including: Australia, Austria, Belgium, Canada, Czech Republic, China, Denmark, Finland, France, Germany, Greece, Italy, Japan, Kingdom of Saudi Arabia, Lithuania, Malaysia, Netherlands, New Caledonia, Norway, Poland, Portugal, Republic of South Africa, Serbia, Singapore, Slovenia, Slovakia, South Korea, Spain, Sweden, Switzerland, Taiwan, United Kingdom and U.S. For a partial reference list of Trimble VRS installations visit: http://www.trimble.com/vrsinstallations.shtml.
Established in 1893, Switzerland's Federal Office of Topography (swisstopo) is responsible for all geographical reference data and products. Swisstopo creates and maintains the geodetic, topographic and geological data for Switzerland including publishing the national map series at a variety of scales and keeping them current. Swisstopo's Federal Directorate of Cadastral Surveying division oversees the official cadastral survey, providing the measurement and mapping for the national land register. Swisstopo forms part of the armasuisse group within the Federal Department of Defense, Civil Protection and Sport (DDPS). For more information, visit: http://www.swisstopo.ch/en
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 the need for field base stations 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.
