Design of Static Star Simulator and Proposes A Technique of Correction Method for the Position of Star
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.
