This is a list of past and present satellites of the BeiDou/Compass navigation satellite system. As of December 2023[update], 44 satellites are operational: 7 in geostationary orbits (GEO), 10 in 55° inclined geosynchronous orbits (IGSO) and 27 in Medium Earth orbits (MEO). Furthermore, 8 satellites (4 in Medium Earth orbit, 2 in geostationary orbit and 2 in inclined geosynchronous orbit) are undergoing testing or commissioning.
Constellation design
For BeiDou-1, the system consists of 4 GEO satellites (3 active + 1 spare).[4]
For BeiDou-2, the nominal constellation consists of 35 satellites (27 MEO, 5 GEO for BeiDou-1 compatibility, 3 IGSO).[5]
For BeiDou-3, the nominal constellation consists of 30 satellites (24 MEO, 3 GEO, 3 IGSO).[1] The constellation was declared "complete" on 23 June 2020.
