  1. Reprocessing of GFZ Multi-GNSS product Zhiguo Deng Mathias Fritsche, Galina Dick, Jens Wickert and Harald Schuh Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum (GFZ) deng@gfz-potsdam.de

  2. GBM Reprocessing • Multi-GNSS data reprocessing. • GNSS systems: GPS, GLONASS, Galileo, BeiDou, QZSS. • IGS-Rapid like daily solutions with ~ 120 sites, IGS + MGEX data archives.

  3. GBM Reprocessing • Number of stations used for each satellite varies from 10 to 130 • Number of satellites is up to 77.

  4. GBM Orbit Validation • 00:00 • 06:00 • Orbit comparison • Difference with GFZ official product • 2) Orbit overlap • 3D position difference between consecutive days at midnight • 3) Orbit fit RMS • 2-day orbit fitted through positions of 2 consecutive days • 4) Satellite Laser Ranging • Day 0 • Day 1 • (L. Prange, 2014 IGS workshop)
