AGNES
Instead of providing a user with the new reference frame LV95 in a classical manner with site descriptions and coordinates, it is also conceivable to provide LV95 using permanent and stable GNSS stations. The result of this approach was the Automated GNSS Network for Switzerland (AGNES).
Goals
The main goals are:
- For surveying, AGNES is an online realization of the new reference system CHTRS95. Continuous observations provide a long-term contribution to the determination of the kinematic model CHKM95 for the Swiss geodetic reference system CHTRS95
- In cadastral surveying, AGNES should promote the use of the new reference frame LV95 and help advance the rapid change from the old to the new reference system (see project «Transfer of the Cadastral Survey into LV95»)
- AGNES forms the basis for the swipos Positioning Service
- Scientific applications in geodynamics and atmosphere research
The 30 AGNES stations are operating and cover the entire country. Detailed information to the individual stations can be obtained by clicking on the desired station. Information concerning the status of the AGNES monitoring is also available.
Concept
The data of the individual AGNES stations are transmitted online to a common analysis center at swisstopo. The computation and control center at swisstopo provides continuous monitoring of the AGNES stations and sends error messages in case of faulty or erroneous data. Because the transmission of the AGNES data operates via the intranet of the federal administration and access from outside the firewall is denied due to security reasons, the data must be outsourced through the firewall to the Federal Office for Computer Science (BIT) on a communications server. From there the user can access the data either offline (post processing applications) or online via GSM (real-time applications).
