GPS／CoMPASS／SINS深度组合研究

摘要

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 integrated navigation system of satellite navigation system / SINS has higher precision,the method of deep integration is used, and networked satellite navigation system of GPS and COMPASS, through the simulation of three kinds of Caiman filter algorithm, the UKF algorithm has higher precision. Through the analysis of multipath effect of satellite navigation system,the method of SINS auxiliary satellite navigation system to weaken the multi path effect is used, and it is concluded that the method can effectively weak the multi path effect.
