S government once the war break out, so the guidance bomb shouldn\'t depend on GPS system completely. The information fusion of MINS/RDSS/GPS multi-sensor integrated navigation has been researched and an improved incoordinate interval federated filter has been proposed creatively.

4在MINS/GPS组合中由于MEMS惯导精度较低，离开了GPS就无法单独导航，但采用GPS系统战时会受制于人，因此制导****的导航系统不能对其完全信赖。

In the process ofnavigation of INS/Scene Matching the aerocraft will save the land information of undersurface offly orbit in the memorizer which has been scouted in advance. While the aerocraft fly thescheduled position the sensor schlep will take the real time image like as RAR image. After thenthe real time image will match the reference image which has been stored beforehand and hasgeographic relation with real time image. Thus the position or horizontal and longitudinal distanceerror of the aerocraft can been fixed on. After that the navigation and control and guidance iscomplete.

在INS／景象匹配组合导航系统的导航过程中，飞行器首先将预定飞行轨道下面事先侦察到的一系列地面图像信息存到飞行器的存储器中，然后，当携带相应传感器的飞行器飞行到预定的位置时，便获取实时图，然后将实时图和预存的已知地理信息关系的基准图进行匹配比较，这样就可以确定出飞行器的当前位置或者偏离预定位置的纵向和横向偏差，从而完成导航和制导功能。

A kind of combined navigation system for the XAUT·AGV100 developed by our institute was designed through the analysis of commonly used guiding styles of mobile robot, adopting coders and gyroscope to provide real-time guiding information to realize the path tracking, apperceiving the environment messages at the task points and part feature points by ultrasonic sensor to position.
