Along with the gradual deployment of new GNSS constellations, the International GNSS Service (IGS) has pursued the extension of its GPS and GLONASS work into a true multi-GNSS service. Supported by numerous national agencies and individual institutions a global network of more than 200 monitoring stations has been established, which supports tracking of Galileo, BeiDou, QZSS, in addition to the legacy navigation systems. In the frame of the IGS Multi-GNSS pilot project (MGEX), six analysis centers (ACs) are now generating precise orbit and clock solutions for new constellations. Out of these, three ACs provide comprehensive multi-GNSS product covering all five constellations. The presentation discusses the deployment and capabilities of old and new GNSSs and describes the status and achievements of the MGEX project within the IGS. The orbit and clock product quality of new GNSS constellations is addressed and remaining limitations for their use are identified. Special attention is given to the prospects of Galileo, which is close to completing a full constellation and offers high accuracy signals for precise point positioning users.
