Abstract:

The navigation method based on stellar refraction is a promising method. The real refraction star map is unpractical because of the costly experiment of spaceflight. To solve this problem, a simulative method of refraction star map is presented in this paper. In this method, the refraction angle of starlight is calculated by combining the atmospheric refraction model and the starlight refraction geometric equation, and the declination and declination can be achieved. Then we can get the refraction stars position on the image plane of stellar sensor by using the star map simulation method. The sensor noise and environment noise are considered in this method and which has been verified by the simulation results.
