  • In this paper, through calculation of the attitude parameters of star tracker, the observed star extraction and star map simulation were realized. The image point was taken gray diffusion according to the 2D Gaussian distribution model. Considering the influences of noise, the real sky star map taken by star tracker on orbit was simulated in real time. Experiments show that the star map obtained through simulation of the real one taken by satellite on orbit could provide confirmation for algorithm of star point extraction, star map recognition and attitude solution of the star sensor.
