摘要: 阐述了GPS(Global Positioning System)/DRS(Dead Reckoning System)/MM(Map Matching)车辆组合导航定位系统组成和车辆定位算法,提出了利用Kalman滤波和非Kalman滤波算法修正测量元件参数,解决了测量元件参数的漂移问题.仿真实验表明该方法具有较好的修正效果.Abstract: Composing of GPS(global positioning system)/DRS(dead reckoning system)/MM(map matching)integrated vehicle navigation and location system and vehicle positioning algorithm were expatiated. Kalman filter and non-Kalman filter algorithm for sensors parameters modification was represented, and the problem of sensors parameters drift was resolved. Simulation indicated good modification result.
