Abstract: In order to conduct ground calibration and accuracy testing for very high accuracy star sensor, a very high accuracy star simulator is put forward, which simulation accuracy is better than 0.5". Star map display and control system is the key component of the star simulator. According to the requirement of simulation accuracy, the star plate is proposed to be used as a map display device. By using a luminescence apiece controllable LED array as the target illumination system, the very high accuracy star map is simulated successfully. At the same time, the software is developed to control each LED light out/on and its gray value, which has completed the transformation for star map and magnitude simulation. Experimental results show that the map display can reach a precision less than 0.5", and can realize dynamical change and magnitude simulation, which has been able to meet the requirement of very high accuracy of star sensor ground calibration and accuracy testing.
