The BeiDou Navigation Satellite System (BDS), also known as BeiDou-2[1], is China’s second-generation satellite navigation system[1][2] that will be capable of providing positioning, navigation, and timing services to users on a continuous worldwide basis[3].

Although the evolution of its regional navigation system towards a global solution started in 1997, the formal approval by the Government of the development and deployment of BDS System was done in 2006 and it is expected to provide global navigation services by 2020, similarly to the GPS, GLONASS or Galileo systems.[1]

As of December 2011, the BeiDou system was officially announced to provide Initial Operational Service providing initial passive positioning navigation and timing services for the whole Asia-Pacific region with a constellation of 10 satellites (5 GEO satellites and 5 IGSO satellites)[4][2]. During 2012, 5 additional satellites (1 GEO satellites and 4 MEO satellites) were launched increasing to 14 the number of satellites of the constellation. Until 2020, the system is going to launch the remaining satellites and evolve towards global navigation capability.[5][4].
