Euref eumetnet mou
EUREF – EUMETNET MoU

  • Signed at EUREF06 in London

  • Good bases for further collaboration between E-GVAP and EUREF


Monitoring nrt solutions
Monitoring NRT solutions

  • Only graphical adaptations to new corporate design

  • New internet system planned till end of the year


Processing
Processing

  • Bernese Software 5.0 (+)

  • ~ same number of stations

  • Absolute antenna model since GPS week 1401 (Nov. 2006)

  • GNSS PP analyses (GLONASS ambiguities float) since week 1401

  • GNSS enhancement of AGNES in June/July 2007: 2/3 of the stations with GNSS receivers equipped

  • GNSS NRT analyses(GLONASS ambiguities fixed) since 2 weeks

Summary
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.


Action items
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
