To reduce the effects of various error factors and improve the pointing precision, a star sensor error calibration algorithm was presented. Based on analysis and generalizing the typical error of star sensor, the ideal and real model of star sensor were constructed. The calibration errors such as the bore-sight offsets, inaccurate focal length of optical system, plane tilt and rotating of focal plane, and optical lens distortion etc, which were separated by the least squares optimal estimation method and the principal of star distance invariability in star catalog. The simulation results indicate that the error caused by not having an ideal model and calibration of the optics could be estimated, the calibration accuracy is improved.
