Paper Abstract

In order to achieve continuous attitude information of the spacecrafts or the telescopes, the star-sensors and the gyros are usually integrated to form navigation systems, which measure and determine the attitude-angles synthetically. The space combinations of the measure-vectors of the star-sensors and the gyros are analyzed to find out the influences of the combination modes on the determination precision of the attitude-angles, and the influence trends are summarized. Furthermore, the optimum space combinations of the measure-vectors are proposed for improvement the determination precision of the attitude-angles and the redundancy/complement of star-sensors and gyros. The optimum space combinations of the measure-vectors are benefit for designing optimum integrated star/gyro systems to achieve high determination precision of the attitude-angles, even any of the star-sensors or the gyros works with poor measurement precision, so as to improve the reliability of the navigation systems.
