Abstract

Abstract

Impact of attitude and pitch misalignment parameters on FY-2 image navigation is studied with simulation method. The simulation result indicates that the parameters affect navigation result orderly; inappropriate parameter assignment will not only result in image displacement but also cause image distortion; different parameters affect image navigation in different ways. Parameters simulated also result in a series of typical images, that is very useful in image navigation error diagnosis. Based on this and other simulation studies, an image navigation model is established, and the automatic operation of image navigation for FY-2 meteorological satellite is realized with high accuracy.
