Paper Abstract

To get high-precision attitude of the spacecrafts in high dynamic maneuver, a double-FOV(field of view) star sensor is proposed. It is composed of two lenses and two image sensors. The star images of the smaller FOV are used to estimate the attitude of the spacecraft for high-precision, and those of the larger FOV are used to speed the star identification process. Moreover, when the smaller FOV can not capture enough stars, the stars in the larger FOV can be used to estimate the attitude of the spacecraft, which enhances the robustness of the star sensor. The simulation results show that the star sensor can provide high-accuracy attitudes while the spacecraft is in high dynamic maneuver stage.
