Abstract: A positioning and orientation data analysis system for air vehicles includes an image sensor module, a positioning and orientation module, and a processor module. The image sensor module captures a map image of a region and has an internal direction parameter. The positioning and orientation module generates a positioning and orientation external direction parameter from external satellite positioning information and navigation coordinate information that it tracks. The processor module, which is electrically coupled to the image sensor module and the positioning and orientation module, generates an image external direction parameter by using aerial triangulation of the map image; and then, by comparing this parameter with the positioning and orientation external direction parameter, generates a boresight angle parameter and a lever arm parameter.
