Abstract

Aiming at solving the problem that the measurement accuracy and veracity of the star sensor is seriously affected by stray light for a geocentric pointing three-axis stabilized satellite, this paper analyzed how the sunlight and the moonlight impacted on the star sensor during the satellite on-orbit running. This method is proposed on basic of studying geometric position of Sun, Earth, Moon and the satellite, considering several elements including the satellite attitude, the star-sensor installation location and field of vision(FOV). Moreover, according to the layout of star-sensor, recommended plans at different time are discussed and given, which can avoid bad influences of stray light effectively.
