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 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 2012.[3]

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.[3][5]

The Chinese Government considers satellite navigation as strategic in the new generation information technology, and encourages international cooperation to ensure compatibility and interoperability with other navigation systems.[3]
