This paper presented and probed into algorithms from two vector observation based on star sensor, including QUEST algorithm and algorithms using Extended Kalman Filter(EKF) with gyros measurements, were derived respectively. And validated higher accuracy of filtering algorithm using star sensor and gyros comparing with the QUEST algorithms through simulation test.
