基于北斗接收机的车载卫星导航系统的设计

基于北斗卫星导航系统、北斗地基增强系统、移动通信网络，设计开发了一款小体积、高精度车载导航系统。主要在接收基站差分信息以及实现高精度定位方面进行探索。通过单点定位和差分定位的野外跑车对比试验得出，该系统性能稳定、可靠性高，其差分定位精度能够满足车辆导航的要求。

Design of Vehicle Satellite Navigation SystemBased on BeiDou Satellite Receiver

Based on BeiDou satellite navigation system, BeiDou ground based augmentation system, mobile communicationnetwork, a small volume and high precision navigation system is developed. This paper mainly explores theways on differential information reception from base station, and high precision positioning realization. The field vehiclecontrast test on point positioning and differential positioning, shows that the system has stable performance and high reliability.Differential positioning accuracy of the system can fully meet the requirement of vehicle navigation.
