The Compass Navigation Satellite System (CNSS), or BeiDou-2, is China’s second-generation satellite navigation system capable of providing continuous, real-time passive 3D geo-spatial positioning and speed measurement. The system will initially used to provide high-accuracy positioning services for users in China and its neighbouring regions, covering an area of about 120 degrees longitude in the Northern Hemisphere. The long-term goal is to develop an independent global navigation satellite network similar to the GPS and GLONASS. [1]
COMPASS Arquitecture
The main layers of COMPASS architecture are:
The space segment consists 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 GSO (IGSO),that will offer complete coverage of the globe.[2]
The ground segment consists of a Master Control Station, an Upload Station and several Monitor Stations.[3]
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]
