Abstract According to the flight characteristics of vehicle under high dynamic conditions, the impact of linear, angular, and vibrational motion on star sensor imaging was researched. Then, the mathematical model of motion blur corresponding to various flight conditions was deduced, and the star centroiding accuracy affected by motion blur was analyzed subsequently. On this basis, the mechanism of multiple blur was discussed. In order to ensure the accuracy of star sensor in high dynamic environment, a restoration method was proposed to remove the multiple blur. Finally, simulations are implemented to validate the restoration method.
