Title: Research on Star Tracking Algorithm Suitable for Star Sensor
Abstract: A novel star tracking algorithm is presented to solve the problem of obtaining location of star slowly in the course of Lost-in-Space case,as well as reducing the time spent in calculating the attitude of spacecraft.The knowledge of recognized stars in previous star image could be used to obtain the knowledge of observed star in current star image with the star tracking algorithm based on the fact that the sufficient attitude knowledge including location of recognized stars in star image could be obtained by star sensor after Lost-in-Space case.The simulation results show that the algorithm in this paper not only reduces the time spent in obtaining location of star to improve update rate of attitude,but also avoids fault star identification with Lost-in-Space case.
