“…This system is often used in calibration experiments of star map recognition ability of star sensors [2]. With the in-depth application of star sensors in remote sensing surveying [3], space-based attack and defense [4], and deep space exploration [5], their attitude determination accuracy has exceeded the second level and has become a development trend. Therefore, improving the accuracy of star position simulation in star simulation systems has become an urgent need.…”

The accuracy of star position simulation in star simulation systems is a key factor affecting the accuracy of ground calibration experiments for star sensors. In order to solve the problem that the current simulation star position accuracy is restricted by the size of its constituent elements, In this paper, the mathematical model for simulating the star position correction and the gray distribution of the constituent elements is derived, and the functional representation of the azimuth and longitude correction, elevation and latitude correction of the simulated star position is established. Exploring the distribution law of star position simulation error and establishing a corrected sub interval based on it, achieving sub pixel level star position simulation accuracy. The experimental results show that after using the method proposed in this article, the accuracy of star position simulation has been improved by 1.74 times.
