An All-sky Autonomous Star Map Identification Algorithm Based on Genetic Algorithm

As a spacecraft attitude measurement instrument,CCD star tracker has a lot of advantages.But it needs an all-sky autonomous star map identification al gorithm to support its operation.The existing star map identification algorithm can be considered as a mode identification method.The article considers the sta r map identification as a combined optimal problem and tries to solve it by mean s of genetic algorithm.The simulation results show that compared with the exist ing star map identification algorithm,the algorithm presented in the paper has the advantages of robust and real time properties and it only needs a sams sized dat abase.
