| Summary: | Star trackers represent the most prominent class of attitude sensors. They provide three axis attitude information with high precision. This study addresses various issues on developing improved star tracker software, presents new approaches for better performance of star trackers, and considers applications to realize high precision attitude estimates. Firstly, a guide star selection method is developed, which generates a new star catalog containing a near minimum number of guide stars for star trackers. Using this guide star set, a new star pattern recognition method is developed for the most general lost-in-space mode. Furthermore, a recursive star pattern recognition method is developed for fast star acquisition and star pattern recognition. Finally, to utilize accurate attitude information from a high frame rate star tracker, a recursive attitude prediction method is derived without any assumption about system dynamics. |
