A Staring Tracking Measurement Method of Resident Space Objects Based on the Star Tacker
Photonics, 2023 Measuring resident space objects (RSOs) by star trackers has become a research hotspot in space situational awareness. However, the arc length measured by star trackers is too short to complete the high-precision orbit determination of the RSO.

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 ...
