Yes. All C4G CORS support four constellations: GPS (U.S. Navstar), Glonass (GLN), Galileo (GAL), and BeiDou (BDS). Rovers using C4Gnet.XYZ mountpoints with "GREC" in their name can use these additional satellite vehicles (SV) in their solutions. VRS mountpoints only support GPS and GLN, so rovers need to connect to a mountpoint that starts with PPP followed by GREC that delivers corrections in CMRx or RTCM 3.2 with Multi-Signal Message (MSM) format to use these additional SVs.
