Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144), 2002 Describes the Intelligent Star Tracker System. The Intelligent Star Tracker System incorporates an adaptive optic catadioptric telescope in a silicon carbide housing. Leveraging off of the active optic technologies, the novel active pixel position sensors (APPS) enable wide dynamic range and allow simultaneous imagery of faint and bright stars in a ...
