The Compass Navigation Satellite System (CNSS), or BeiDou-2, is China’s second-generation satellite navigation system capable of providing continuous, real-time passive 3D geo-spatial positioning and speed measurement. The system will initially used to provide high-accuracy positioning services for users in China and its neighbouring regions, covering an area of about 120 degrees longitude in the Northern Hemisphere. The long-term goal is to develop an independent global navigation satellite network similar to the GPS and GLONASS. [1]
COMPASS Arquitecture
The COMPASS User Segment consists of COMPASS/Beidou user terminals, which receive Compass navigation signals, determine pseudoranges (and other observables) and solve the navigation equations in order to obtain their coordinates. A COMPASS Receiver is a device capable of determining the user position, velocity and precise time (PVT) by processing the signal broadcasted by Galileo satellites. Any navigation solution provided by a GNSS Receiver is based on the computation of its distance to a set of satellites, by means of extracting the propagation time of the incoming signals traveling through space at the speed of light, according to the satellite and receiver local clocks.[2]
There is also an international cooperation in terms of Compatibility and Interoperability between BeiDou and other GNSSs, that will lead to interoperable terminals compatible with other GNSSs.[3]
