The Multi GNSS Experiment (MGEX) was initiated by the IGS in 2012. In MGEX all available signals of the new GNSS satellites are analysed. Currently, seven IGS analysis centers generate consistent and precise orbits and clock corrections of the new satellites (Montenbruck et al. 2017). As one of these seven analysis centers, GFZ processes all satellites of the global navigation satellite systems GPS, GLONASS, Galileo, BeiDou and QZSS in near real time and in post processing (Deng et al. 2016). Currently our combined analysis contains nearly 90 satellites, for the first time, providing the worldwide public user community with unified satellite orbits and clock parameters.
