Paper Abstract

The starlight refraction navigation is considered to be one of the most promising methods for satellite autonomous navigation. This paper mainly did research on the capture of navigation stars in starlight refraction navigation. By studying on the geometry relation between measurement star and satellite, a measurement star orientation method can be deduced which can be used to simulate the actual orbital navigation. According to this method the measurement star can be obtained at any satellite position. Then the measurement information can be modeled through which the laboratory digital simulation of starlight refraction navigation and integrated navigation can both be performed. At the mean time, confirm the navigation measurement starlight orientation combined with the star catalog. Then use starlight refraction navigation to calculate the satellite positions and velocities based on the Unscented Kalman Filter. At last, use the starlight refraction and starlight elevation integrated navigation based on the information fusion method to resolve the matter that the refraction measurement star can not be captured. Compared with merely using starlight refraction navigation, the precision of integrated navigation can be effectively improved.
