  1. EUREF’04: National Report of Switzerland • D. Schneider • E. Brockmann • W. Gurtner • Schlatter • B. Vogel • Wiget • U. Wild

  2. Permanent GPS network (AGNES) Fundamental station Zimmerwald • Contribution to ECGN: Collocation of various geodetic observations (see paper by E. Brockmann) • High performance: Average of data availability: > 99 % • 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) EUREF'04 Bratislava

  3. SAPOS APOS swipos 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 EUREF'04 Bratislava

  4. Analysis of permanent GPS networks • Networks: • GPS Meteorology: European collaboration within research projects COST-716 and TOUGH EUREF'04 Bratislava
