| The dynamic star simulator is a very important test equipment be used in the demarcated detection between the ground and star sensor. Its level of precision influence the satellite control system’s attitude measurement directly. The dynamic star simulator not only can simulate the star map infinity, but only can simulate the star magnitude star map and coordinate position completely. By compare the operative mode between stimulative starry sky and star sensor, complete the timed detection of star sensor.In this thesis, analyze the forms of the dynamic star simulator, its overall structure and the operating principle, develop the research deeply of the display system of the star atlas and the main reasons which can effect the precision of the display resolution of the dynamic star simulator. Set up a hardware circuit of the dynamic star simulator’s display system, and have an excogitation of it. Complete the research which based on using the method of sub pixel for improving the system accuracy, provide the correction curve of the location of the stars after the partition of the star atlas by design the display correction software of the star atlas, can improve the imitate precision of the star atlas effectively and proving it by the experiment. |
