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 User Segment
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 COMPASS 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]
Applications
GNSS applications are all those applications that use a GNSS signals to collect position, velocity and time information to be used by the application. For instance, the position and velocity provided by a COMPASS user terminal may be used for different kinds of applications (civil, military, scientific) such as:[3]
- Fishery: Fishermen safety of life, Oceanic and economic security, Protection of marine resources and sovereignty.
- Disaster Prevention and Mitigation: improvement of rescue response and decision-making capability due to rapid and timely disaster alert, rescue command scheduling and rapid emergency communication.
- Timing: Beidou/GPS multi-mode time synchronization devices with embedded Beidou/GPS timing module.
- Transportation: fleet management.
- Water conservancy.
- Meteorology.
- Forest Fire Prevention.
- Soil Monitoring.
- Coal Mine Safety Monitoring.
