Permanent GPS network (AGNES)• High performance: Average of data availability: > 99 %
• Contribution to ECGN: Collocation of various geodetic observations (see paper by E. Brockmann)
Fundamental station Zimmerwald
• Replacement of receivers (Trimble 4000SSI → 4700) resulted in signifi- cantly improved performance of RTK positioning (faster data output)• New station software (GPS-Base Vers. 2.10)

Real time positioning service „swipos“
• International co-operation “D-A-CH”: Seamless positioning service along the national borders to Germany and Austria due to mutual integration of stations of the real-time networks: D: SAPOS, A: APOS and CH: swipos
• Data exchange between the control centers: SAPOS (BW) in Karlsruhe, SAPOS (BAY) in Munich, APOS in Vienna and swipos in Wabern.
• Delivery of RTCM data of station Zimmerwald to EUREF-IP over Internet• Development of a monitoring device for assessing VRS/RTK

Analysis of permanent GPS networks
• Networks:
EUREF subnetwork 20 -> 25 (1 AGNES) daily observations 21 days
AGNES+ subnet EUREF
65 -> 72 (29 AGNES) daily observations 21 days
AGNES+ subnet EUREF
63 -> 72 (29 AGNES) hourly observations
0.5 hours
• GPS Meteorology: European collaboration within research projects COST-716 and TOUGH
