Abstract
The major task of the Multi-GNSS Pilot Project (MGEX) of the International GNSS Service (IGS) is tracking, collating and analyzing all available GNSS signals. The final goal is the integration of the evolving global and regional satellite navigation systems Galileo, BeiDou, QZSS, and NavIC (IRNSS) into the IGS operational products. The backbone for these activities is a network of multi-GNSS tracking stations available at the IGS data centers. Currently six MGEX analysis centers generate precise multi-GNSS orbit and clock products on an operational basis. Further products include merged navigation data, a dedicated CNAV product for GPS and QZSS, as well as two multi-GNSS differential code bias (DCB) products. This contribution presents the current status of the multi-GNSS tracking network and the MGEX analysis products. Progress in solar radition pressure modeling is demonstrated and evaluated by satellite laser ranging residuals and orbit comparisons. The GNSS providers of Galileo and QZSS have recently published metadata like antenna offsets, spacecraft mass, and transmit power. The impact of these data on the analysis products will be demonstrated. Furthermore, clock analysis of new satellites not covered by the current MGEX products will be presented, namely for the BeiDou-3 and QZSS geostationary satellites.
