英文摘要：

In order to realize the ground calibration tests of star sensors, a ground calibration system of large field of view and high angular distance between stars’ simulation accuracy was designed, the composition of calibration system, optical system design and simulation precision were studied. According star sensors ground calibration requirements the system components was introduced, a method to realize the angular distance between stars’ simulation precision better than that of 20＇＇ was put forward. Using the new display LCOS as star chart display, the image plane field by splicing methods was expanded, and Zemax software was used to design the optical system accordingly. On the basis of the original measuring method, the evaluation method of ground calibration equipment precision was given. And a way was proposed to improve the angular distance between stars’ simulation accuracy by the method of star correction. The experimental results show that the star sensor ground calibration equipment of the angular distance between stars＇simulation precision is less than 20＇＇, meet the star sensor for ground calibration test requirements.
