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。
