为了满足 VANET （ Vehicular Ad-hoc Network ）中对车辆位置信息的高精度要求，本文研究了一种基于全球定位系统（ Global Positioning System ， GPS ）伪距双差和有高精度里程仪的惯性导航（ Inertial Navigation Systems ， INS ）的协作相对定位方法。通过数据融合技术，将 GPS 伪距双差、GPS 信号的多普勒频移以及被高精度里程仪修正后的 INS 加速度等数据进行融合处理，获得具有良好精度的相对定位结果。结果表明，使用该方法的定位性能优于无里程仪和 INS 的定位性能。

In order to meet the requirements of vehicle position high accuracy applications in VANET, a relative positioning method based on GPS pseudorange double difference and INS system which adds an odometer with high accuracy in a collaborative manner is studied in this paper. The data fusion algorithm is used to fuse the GPS pseudorange double difference, GPS Doppler shifts and the INS data, thus it highly improves the accuracy of relative positioning results. The results show that the positioning performance of this method is obviously improved compared with the one without the INS and odometer.
