Present star identification algorithms have the problem of real-time calculation. In order to meet the navigation requirement of the upper stage, the K vector search algorithm was employed, the inter-star angles as the matching feature quantity were selected and the star pyramid matching algorithm was used. Finally, simulation results indicate that the success rate of this algorithm is more than 99%, the maximum time of identification is about 100ms, and the average time is less than 15ms. The algorithm can meet the matching speed and precision requirements of the upper stage.
