Paper Abstract

Highly accurate image navigation has become a challenge due to the image distortion and thermal drift perturbations for geostationary satellite wide field-of-view(FOV) instrument with gimbaled mirror scan system. A novel instrument model of image navigation with few parameters is studied under lack of feature points. Its performance is evaluated through instrument star observation outdoors. The experimental results present that the image navigation approach yield high-precision compensation in full field of view. The accuracy is better than 60μrad, which demonstrates the enhanced image navigation capability to be obtained on further satellite missions.
