13 Swiss Federal Office of Topography swisstopo LPT status report EGVAP, Matera Summary Absolute antenna phase center model used since GPSWeek 1400 (Nov. 2006) for NRT and PP. Influence is 4-12 mm dependent of antenna type on the station GNSS processing (ambiguity float) introduced in postprocessed solutions since GPSWeek 1401. The influence on ZTD is very small. 2/3 of the AGNES sites with GNSS receivers New baseline strategy (shorter baselines) is a prerequisite for GNSS ambiguity resolution. GNSS ambiguity fixed solutions since 2 weeks. Influence on NRT need to be validated.

14 Swiss Federal Office of Topography swisstopo LPT status report EGVAP, Matera Action Items Installation of remaining 10 AGNES sites: GPS -> GNSS (double station concept) Ambiguity resolution GNSS for longer baselines and for mixed receivers including proper inter-phase bias handling (-> hope to realize improvements for NRT ZTD + GNSS- tomography) More “Super Sites” in LPT processing
