Beidou continuously operating reference station (CORS) compatible bus precise positioning system and working method thereof

The invention relates to a Beidou continuously operating reference station (CORS) compatible bus precise positioning system. The Beidou continuously operating reference station (CORS) compatible bus precise positioning system includes a Beidou CORS compatible bus precise positioning terminal, a CORS positioning system, a communication service center and a bus background management system; the Beidou CORS compatible bus precise positioning terminal includes a CPU module, a power source module, a Beidou/GPS dual-mode positioning module, an inertial navigation positioning module, a 3G/4G communication module, a touch screen display module and a storage module; and the CORS positioning system includes a base station, a data processing center and a communication gateway 1. According to the Beidou continuously operating reference station (CORS) compatible bus precise positioning system of the invention, the GPS and the CORS are combined together, and therefore, the effectiveness and integrity of the system can be improved; the defect of incapability of performing position when a bus enters a GPS blind area can be eliminated, and vehicle real-time accurate positioning can be realized, and positioning accuracy can reach a centimeter level; accurate positioning data which are obtained in real time are transmitted to a background management center so as to be stored, and therefore, reliable data can be provided for the generation of bus roads.
