为验证卫星导航系统/SINS组合导航系统具有更高的精度,采用深度组合的方法,利用技术比较成熟的GPS与我国正在研发的COMPASS组网形成的卫星导航系统,通过对3种卡尔曼滤波算法仿真实验,得出了平淡卡尔曼滤波算法具有更高的精度。通过对卫星导航系统多路径效应的分析,采用SINS辅助卫星导航系统消弱多路径效应的方法,得出该方法可以较好地消弱多路径效应。
In order to verify the high accuracy of the satellite navigation system / SINS integrated navigation system, a deep combination method is used to make use of the satellite navigation system formed by the comparatively mature GPS technology and the COMPASS network under development in our country. Three kinds of Kalman filter algorithms Simulation experiments show that the flat Kalman filtering algorithm has higher accuracy. By analyzing the multipath effect of satellite navigation system and using SINS-assisted satellite navigation system to weaken the multipath effect, we conclude that this method can weaken the multipath effect better.
