摘要

The paper reviews main errors of star trackers and their characteristics, provides a method of calibration, comprising a plurality of consecutive rotation turns at a small angle increment in the range of ± 200 arcseconds. A test bench model for star trackers is presented. Analysis of the influence of spatial instability of the angle-setting rotary table axis of rotation on calibration results of a star tracker is conducted.
