摘　　要：通过分析传统的GPS和车辆航位推算导航系统定位方法的不足,提出使用GPS/DR组合导航技术来获取定位数据,并使用一种新的数据融合方法优化定位数据,通过CDMA1X无线数据网络改善传输方式。经过实验验证,此优化方案为车辆的实时监控提供了稳定可靠的实时数据传输,提高了ITS系统的性能。Through analyzing the deficiency of traditional location method using GPS and DR navigation system, this paper proposes a combined GPS/DR navigation technique for obtaining location data. A novel data fusion method is used for optimizing location data, and the transmission is improved by means of CDMA 1X wireless data network. Experimental results show that this design provides stable and reliable real time data transmission for real time monitoring of vehicles and improves the performance of ITS systems.
