| Abstract: | According to the requirement of star sensor ground calibration equipment,this paper designed a high-precision and full-spectrum magnitude simulator based on digital control. The system adopted the collimation optical system with no distortion and high imaging quality to simulate the "infinity" starlight;based on pulse width modulation ( PWM) technology,the hardware and software of the drive circuits were designed. Test the star simulator under darkroom condition, the results showed 15 magnitude gear ( 0, 0. 5, 1,…, 6. 5, 7 ) can be combined regulation as well as separate regulation,simulation precision was ±0. 1m. Control distance was 10 m, control error was not exceed ±0. 1%. |
