Author Affiliations +
CMOS APS based star tracker is a new generation of attitude sensor. An APS based autonomous star tracker has been proposed. This paper gives a primary demonstration of the software performance of the proposed star tracker, through laboratory and real night sky experiments. The star pattern recognition algorithm in the software protocol uses a quick search and robust match strategy and can perform independent star identification without prior attitude knowledge. The laboratory experiments validated the whole sky independent star pattern recognition algorithm and showed a comprehensive influence of errors and noise on the software performance. The real night sky experiments tested the sensitivity of the APS star sensor and validated the feasibility of the star identification and attitude estimation algorithm. In this paper, the structure and procedure of the software is described. The experiment system setup is introduced and the results of the laboratory and real sky experiments are presented and discussed.
