摘要
This paper focuses on recognizing the correct match of star identification among multiple possible candidates for star trackers. Derived from the perturbation theory, a tolerance criterion is proposed and proved to check the correctness of the candidates. A recognition algorithm is then proposed based on the tolerance criterion to select the correct match. Compared to traditional recognition algorithms, the proposed algorithm provides a straightforward and deterministic procedure and avoids non-deterministic, time-consuming, inefficient lookingup operations. Finally, simulation examples are given to show processing details and verify the proposed algorithm.
