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]
Although the upgrade of its regional navigation system towards a global solution started in 1997, the formal approval by the Government of the development and deployment of BeiDou-2/CNSS was done in 2004.[1] The system is currently under development evolving from a regional system called BeiDou-1, and in the first phase will provide high-accuracy positioning services for users in China and its neighbouring regions by 2012.[1] In a second stage, the system will evolve to provide global navigation services by 2020, similarly to the GPS, GLONASS or Galileo systems.[1]
As of August 2011, nine satellites for Compass have been launched, the first eight of which completed the deployment foreseen for the first phase of BeiDou-2.[1][3][4]
COMPASS Architecture
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.[3]
The ground segment consists of a Master Control Station, Upload Stations 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]
