G-Nut/Anubis application

G-Nut/Anubis is a command-line tool for a quality check of modern data from all available GNSS constellations providing full quantitative and qualitative control with and without support of GNSS navigation messages:

  • observation statistics (list/counts of observations, signals, bands, satellites of GPS, GLONASS, Galileo, BeiDou, SBAS, QZSS)
  • standard point positioning if supported with navigation messages (GPS, GLONASS, Galileo and BeiDou)
  • clock-jumps, cycle-slip detection and other interruptions (all constellations/frequencies/signals)
  • satellite elevations and azimuths if supported with all constellation navigation messages
  • code multipath (moving average RMS)
  • data gaps and small data pieces
  • other useful lists and statistics

The application is implemented using the G-Nut core library developed at Geodetic Obsevatory Pecny (GOP) and released under GNU GPL.
Anubis configuration and outputs are described under sub-menu (see main menu left).
