摘要：Due to the intense vibration and/or the change of space environmental factors such as temperature, pressure, etc., the stellar camera parameters might change during satellites launching or while orbiting the earth, which causes the decline of satellite attitude accuracy. So the on-orbit calibration is essential for the stellar camera. In this paper, the selection of star image for on-orbit calibration is discussed. From experiment, it can be concluded that for the on-orbit calibration based on space resection, the distribution of star image points has strong effect on the calibration accuracy, and a good selection of images can significantly improve the calibration accuracy
