摘　　要：BDS(Bei Dou Navigation Satellite System)是我国自主研制的新一代卫星定位系统,其应用技术对我国车辆定位产生重要影响.为了适应车辆对实时精确定位的迫切需求,提高基于BDS/GPS车辆定位系统精度及可靠性具有重大意义.本文设计了基于BDS/GPS的车载定位终端装置,该装置包括BDS/GPS定位模块、GPRS无线通讯模块、ARM9处理器,通过扩展卡尔曼滤波算法提高定位精度,实现亚米级(1米)定位,实验结果证明了该作品已基本满足要求.BDS is a satellite positioning system which is independently developed by China. The construction and development of BDS will have an important impact on methods of vehicle positioning in China. In order to meet the urgent needs of real-time precise positioning for the vehicle positioning system, enhancing the positioning accuracy and reliability of vehicle positioning system. The BDS/GPS has practical significance. This paper designs a vehicle terminal based on BDS/GPS, which including BDS/GPS module, GPRS module and ARM9. Using the extended Kalman filtering algorithm to process the processed data can improve the positioning accuracy and realize the sub-meter level （within 1 meter）. The experimental results show that the terminal can achieve high-precision positioning.
