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]. Overall, the BeiDou system covers both regional and global services and it is being developed in an incremental way. The deployment of the system started with the regional services (covering China and its neighbouring regions) and Full Operational Capability (FOC) is expected to be reached by 2020.
BeiDou Services
The BeiDou supports both global worldwide services and regional services.
The global services can be further sub-divided in two other services[4]:
- Open Service
The Open Service is similar to GPS and Galileo and it is free of charge and open to all users worldwide. Users are able to compute their navigation solution using the same principles as for GPS and Galileo and the system is designed to provide a position accuracy of 10 meters, a timing accuracy of 50 ns and a velocity accuracy of 0.2 meters per second[5].
- Authorized Service
The authorized service aims at ensuring high reliable use even in complex situations and there is little information about it.
As far as regional services are concerned:
- Wide area differential services
These services are foreseen for BeiDou and advertised to reach one meter positioning accuracy. Wide Area Augmentation is supported by BeiDou regional system: 30 stations broadcasting corrections by GEO and providing Cat I service in 2012[6]. The current status of China GNSS Augmentation system reported in 2011[6] includes 21 coast stations providing 5 meters service for near sea ships.
- Short message service
Short message service, also called Positioning Report Service, is supported by BeiDou-1 and consists in allowing the user and the station to exchange short messages (currently 120 Chinese characters per message). This service will probably be provided by BeiDou and may evolve to longer messages and not limited to position report.
