  1. AMON Reprocessing Hybrid IGS05+IGS08

  2. EPN Reference Criteria: Long history ReliableTimeSeries Minimal gaps Geographicaldistribution Other neighbour EPN stationsadded: GOPE, GSR1, MEDI, MOPI, TUBO, VACO

  3. AMON Site Handling Bernese Software 5.0 (BSW) Orbits + ERP reprocessed IGS05 Reference coordinates + velocities IGS08 Using BEV logsheets Same strategyas in EPN analysis Daily results Weeklyresults separate run Startingwithyear 2006, back to 1998 – firstrun Keepingoldsitenames (e.g. TRFB insteadof TRF2) Problem ofantennaheightconsistencylogsheet – STA-file of BSW

  4. Detected Problems • Not yet all BEV logsheetsincludedinto STA-files – inconsistencies • Overlappingtimes in BEV logsheets (e.g. BLEI-BLE2) and different antennaheights • Individual antennacalibrations not alwaysapplied (dummyantennanumbers in STA-file, not 5 digits in RINEX files, semi-automaticpreprocessingneedsmanualinterferenceandisconsuming human time) • Not all problemsvanish (equipment, snow), somenewappear, same experienceas in EPN repro1 • Strange EPN site TUBO (constant 5-10 cm differenceto a priori IGS08)

  5. First Results • Processing time 1 day = 1 hour • StartingwithJanuary 1st 2006, presentlyabout 50 days • Total of 80 stations • About 5 stationswith large (>5 cm) differences, 3 EPN sites (JOZE-snow?, MOPI-snow?, TUBO?) • About 5 stationswith moderate (2 cm) differences, antennacalibrationorantenna type mismatch? • 70 stationscoincidewithin 10 mm into AMON solutionof 2011!!! • Significantlyimprovedsolution (height)
