基于POSAV610与PPP的车辆导航数据处理

Vehicle Navigation Data Processing Based on POS AV610 and PPP

本文利用POSAV610采集了车辆的位置和姿态数据，其中采用单站双频接收机和精密单点定位方式进行了原始定位数据的采集与后处理，减少了传统方式基站架设的环节与成本。数据采集过程中利用车辆机动模拟航空飞行数据，用POSPacMMS5．4的精密单点定位算法进行后处理。车载实验表明，在卫星信号受到城市建筑遮挡的情况下，与原始采集精度相比，车辆位置和姿态数据后处理精度仍能够得到一个数量级以上的显著提升。

POS AV610 is applied to collect vehicle position and orientation data in this paper. A single station dual frequency GNSS reeiever and precise point positioning （PPP I method are utilized in original position data collecting and post - processing, so that the traditional way of base station construction is simplified and cost is reduced. In the data collecting process, vehicle maneuver is used to simulate aviation flight data while PPP algorithm of POSPac MMS 5.4 is used for post - processing. Experi- ments on vehicle indicate that under the condition of satellite signal being blocked by city buildings, post - processing accuracy of vehicle position and orientation data is notably improved over that of raw data by one order of magnitude.
