The data quality metrics are retrieved from the EPOS-GNSS data nodes where they were computed using the G-Nut/Anubis software. Input files are the daily RINEX (V2 or V3) observation files available from each node. All of the quality plots contain information for the GPS, GLONASS, GALILEO, BeiDou constellations on all available frequencies. Updated daily.
