Star sensors are the most accurate attitude determination instruments in a satellite. The error of star sensor is the key point of the precision of attitude determination system. In this paper,the error sources of star sensor are summarized systematically according to the frequency characteristics. The error analysis,suppression and compensation methods are reviewed so as to provide references for further study. Based on these introductions,the development trend of error suppression and compensation for star sensor's low frequency error and high frequency error is investigated.
