  • In order to test the identification algorithms for a star map and evaluate the performance of a star sensor, a CCD star map simulator was proposed and the star map simulation software was developed in this paper. The system used a high-resolution display device and a parallel light tube to simulate the parallel light of an infinite distance to obtain the high quality star map. The validation on star map by an attitude determination algorithm was also presented. By calculating the attitude angles for three stars more accurately, more than 100 star maps were analyzed. The results indicate that the positioning accuracy has reached 98.1%. The designed simulator has been used in a practical operation, the experimental results show that it can offer good information for verifying star map identification algorithm and evaluating star sensor performance, and it also can shorten the development cycle.
