In addition to the introduction of the basic principle of star sensor and the analysis of the characteristics of the star image, this paper explored into the methods of the guide star identification for star sensor and elaborated the method of the threshold, the connectivity and the centroid for the star locating from the perspectives of theory and practice. A precise test on this method showed that the star sensor would be more precise through the new method of calibration.
