Abstract
A novel algorithm reducing all-sky star pattern recognition´s delay time is proposed. Because of shortages of the all-sky star pattern recognition such as too much delay time and low precision of measured attitude , the novel algorithm can calculate the position of boresight axis´ projection of star sensor when all-sky star pattern recognition is completed and starts a localized star pattern recognition in the area centred at the boresight axis´ projection to improve time delay and precision of attitude. Simulation results show that the novel algorithm has less delay time and more precision of attitude than the traditional all-sky star pattern recognition.
