Abstract

For the new satellite autonomous navigation technology using sensors with functions of a star sensor and an ultraviolet earth sensor, it lacks the device to simulate target characteristics of stars and the earth. In the paper, we proposed a combined simulation device composed with a visible light star simulator and an ultraviolet light earth simulator. At first, the general optical system designing program of simulators was presented after analysis of working requirements. Then, the designing process of optical systems was described in detail. After that, high precision and profile simulation method was analyzed intensively. Furthermore, an accurate correction method for the angular travel error between two stars and earth flare angle error was lay out. At last, the visible light stars and ultraviolet light earth combined simulation device was utilized. The results show that the precision of combined simulation device which can simulate star positions and earth graphics is high. Moreover, the angular travel error between two stars is less than ±7 second of arc. In addition, earth flare angle error is less than ±0.05°. The results meet the function and precision requirements for autonomous navigation of an attitude sensor on satellite. The high precision combined simulation device may meet the basic requirements for ground precision calibration and functional test of an attitude sensor.
