Combined navigation positioning system for vehicle

The utility model provides an integrated navigation positioning system for a vehicle. A first positioning module acquires first positioning data of the vehicle; the second positioning module obtains second positioning data of the vehicle; the first main control module determines final positioning coordinates of the vehicle by combining the first positioning data and the second positioning data; the second main control module transmits the positioning coordinates of the vehicle obtained from the first main control module to external equipment; the second positioning module is an inertial navigation module; the first positioning module is an RTK-GNSS module. The calculation precision of the positioning coordinates of the vehicle is improved, the vehicle is accurately positioned, double master control systems are adopted, higher reliability and real-time performance are provided, the processing efficiency is improved, and the algorithm is easy to arrange. 本实用新型提供一种车辆用组合导航定位系统，第一定位模块获取车辆的第一定位数据；第二定位模块获取车辆的第二定位数据；
