The Compass Navigation Satellite System (CNSS), or BeiDou-2, is China’s second-generation satellite navigation system capable of providing positioning, navigation, and timing services to users on a continuous worldwide basis.
The system has evolved 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. The long-term goal is to develop an independent global navigation satellite network similar to the GPS and GLONASS.[1]
COMPASS Future and Evolutions
By April 2011, the initial phase of COMPASS system has been completed with a constellation of 4 GEO satellites and 3 IGSO satellites. During 2011, the system is going to launch another 4 Beidou Navigation Satellites, providing initial passive positioning navigation and timing services for the whole Asia-Pacific region.[2]
The global COMPASS system will be completed by 2020, with a complete Walker constellation (27 MEOs) plus 5 GEOs and the existing 3 IGSOs satellites of the regional system.[3][2]
