Abstract: The error resources of star sensor, definition of low frequency error (LFE), error analysis and calibration methods are described in this paper. The field of view (FOV) spatial error and thermo elastic error are the main factors in orbital periodic error of star sensor. The LFE of typical star sensor is less than 0.8″ via new methods.

Key words: star sensor, error analysis, low frequency error, calibration method
