| 摘 要： | 针对目前三种主流导航方法各自的不足，提出了一种基于最优滤波法的卫星、惯性组合导航方法，采集这两种导航系统实时测量得到的伪距、伪距率的差值，通过设计合适的最优滤波器，以校正系统误差，获得高精度位置、速度、姿态的用户定位结果，从而弥补了惯性导航误差随时间离散和卫星导航易受外界电磁环境干扰、无法直接提供用户姿态信息的问题。

| Abstract: | Aiming at the shortages of the current three popular navigation methods,this paper proposed a difference of pseudorange and pseudorange rate based satellite and inertial integrated navigation method.This method uses the pseudorange and pseudorange rate measured by the satellite navigation system and inertial navigation system to do optimal estimation, to correct the system error and obtain high positioning results including location, velocity and attitude.Make it up that system error disperse and being easily disturbed and unable to directly export posture information. |
