| Abstract | In order to achieve high-precision ground calibration of star sensors and meet the needs of a high-precision multi-star simulator with a wide field of view, a high-precision star simulator which can accurately simulate the position and magnitude of 65 stars in the 20 40 field of view was developed. Based on the principles of star simulators and the transformation of the space coordinate systems of star simulators, a simulation star bracket was designed. By the analysis and calculation of errors that affect the pointing error of star simulations, the high-precision simulation star system was designed using key technologies such as "integrated installation of primary and secondary mirrors", "all-aluminum simulation star systems" and "star point position compensation". A space-position model of each simulation star in the o-x'y'z' coordinate system was established, and the mathematical models of pitch, yaw, single star direction and star angular distance were derived. Also, the theoretical errors in single-star direction and star angular distance, which were used as the theoretical basis for adjustment and testing, were calculated. The single-star direction error of all simulated stars was better than 1.914", and the angular distance error of any two simulated stars was better than 4.3". The accuracy of the designed high-precision wide-field-of-view multi-star simulator meets the requirements. It can be used as an important piece of equipment for ground calibration of high-precision star sensors. Copyright 2020 Chinese Optics. All rights reserved. |
