Abstract
In order to carry out on site calibration and accuracy test of a high accuracy star sensor, a type of compact very high accuracy star simulator system is needed, and its accuracy should be less than 0.2″. Firstly, we should study on the optical system with high imaging precision. Then, put a high-precision and large size star board on the star display system, in a static form to simulate dynamic star map. Finally, we should design the structure for star simulator according to parameters of optical system, to ensure installation accuracy and reliability of lens. The result shows that all of design indexes meet the requirement, and accuracy better than 0.2″, so star simulator proposed in this paper is satisfied for on site calibration and accuracy test of the high accuracy star sensor.
