为了实现对高精度星敏感器的地面标定，设计了一种大视场静态星模拟器，其星间角距精度要求优于20″。采用星点分划板作为核心显示器件来模拟星图，通过设计大视场小畸变光学系统使模拟星图成平行光出射，在星敏感器入瞳位置产生星图。为保证星点板的星图模拟精度，提出了一种星点位置的修正方法。实验结果表明，经过星点位置修正后的静态星模拟器可以给出星间角距精度优于12″的模拟星图，该模拟器可用于高精度星敏感器的地面标定。

In order to achieve calibration of ground testing on the high accuracy star sensor, the design of a large static viewing field star simulator is described.The star simulator system need to be established, and the requirements of the system′s measurement accuracy is less than 20″. By using star reticle as the core display, a long-focus and large viewing field optical projection system is designed to simulate stars figure into the parallel light ejected, and star maps are produced at the pupil of the this optical system, then a technique of correction method is proposed by using the focus to modify the position of star on the star reticle. Experimental results show that the star simulator can simulate star chart after correcting the star position; the accuracy of angular distance between stars is less than 12″. It can be completely used for the calibration of high-precision star sensor.
