Abstract

The calibration work was important to the development of star sensor, improving the accuracy of star simulator was very important for the calibration of star sensor. In reality, being limited in manufacturing technology, assembling and testing facility and so on, it was very difficult to achieve the precision of design theory, especially the star angular distance. In this paper, from the accuracy of angular distance of star simulator, combined with the installation practice, through real-time monitoring of theodolite, and put forward a quantitative method of focusing. Experimentation have shown that the method can realize the accurately focusing of star simulator, all the angle distance error finally were less than 7.72″, and can improve the installation efficiency.
