Title:
METHOD AND SYSTEM FOR ASSESSING ATTITUDE STABILITY USING LIGHT SENSING OF ON-ORBIT STAR
Document Type and Number:
WIPO Patent Application WO/2022/111227
Kind Code:
A1
Abstract:
A method and a system for assessing attitude stability using light sensing of an on-orbit star, comprising: step S1: after a satellite captures a star, adopting an inertial orientation attitude control mode; step S2: a satellite-borne camera continuously images the target star to acquire target star imaging information; step S3: on the basis of the target star imaging information, calculating theoretical pixel coordinates of the star, and acquiring calculation information of the theoretical pixel coordinates of the star; and step S4: on the basis of the theoretical pixel coordinates of the star, by means of analysing the trajectory of the star image on a detector, assessing the attitude stability of the satellite platform, and acquiring information of the attitude stability assessment result of the satellite platform.
