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 neighboring 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 Ground Segment
The COMPASS Ground Segment consists of:[3][5]
- a Master Control Station: responsible for satellite constellation control and processing the measurements received by the Monitor Stations to generate the navigation message.
- Upload Stations: responsible for uploading the orbital corrections and the navigation message to Compass satellites.
- Monitor Stations, which collect Compass data for all the satellites in view from their locations.
