Aiming at the real-time star tracking problem of missile

a new method for real-time star tracking is proposed.According to the characteristics of star tracking/predicting and tracking mode

firstly

star model catalog based on unified storage is established

and k-vector is used as searching method to improve searching speed;Secondly

in order to real-time generate information set of local star

a parallel multi-dimensional searching method is proposed to save the time of extracting the star image information;Finally

the performance of algorithm is analyzed.Simulation results show that the arithmetic can greatly improve the real-time performance of star tracking

and improve missile precision.
