The Compass Navigation Satellite System (CNSS), also named BeiDou-2, 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.
On November 2, 2006, China announced the 2nd generation Chinese navigation system, COMPASS[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. As of April 2011, eight satellites for Compass have been launched. According to an official report[2], " the eighth Beidou/Compass satellite marks the completion of basic function of Beidou (Compass) Navigation Satellite System " .
The long-term goal is to develop an independent global navigation satellite system similar to the GPS and GLONASS.[3]
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, this will complete the first phase of COMPASS system by 2021.[4]
The global COMPASS system will be completed by 2020, with a Walker constellation of 27 MEOs plus 5 GEOs and the existing 3 IGSOs satellites of the regional system.[5][4]
Among the China State Council's strategies there is the Satellite Navigation Technology as a very important component of the new generation information technology. China encourages international cooperation to ensure compatibility and interoperability with other navigation systems.[4]
