The Compass Navigation Satellite System (CNSS), also named BeiDou-2,[1] is China’s second-generation satellite navigation system that will be capable of providing positioning, navigation, and timing services to users on a continuous worldwide basis.[1][2]
As for the other GNSSs, the main layers of COMPASS architecture are:
- COMPASS Space Segment: By 2020, the space segment will consist of a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 non-GSO satellites; 27 in Medium Earth Orbit (MEO) and 3 in Inclined Geosynchronous Orbit (IGSO), that will offer complete coverage of the globe[3].The system is to be deployed in two stages; the launches for the first phase will be completed by 2012[1] and will consist of 14 satellites[3] .
- COMPASS Ground Segment: The ground segment consists of a Master Control Station, Upload Stations and several Monitor Stations.[3]
- COMPASS User Segment: The User Segment is composed by the BeiDou/Compass user terminals, which receive Compass navigation signals, determine pseudoranges (and other observables) and solve the navigation equations in order to obtain their coordinates. There is also an international cooperation in terms of Compatibility and Interoperability between BeiDou and other GNSSs, that will lead to terminals compatible with other GNSSs.[3]
