Abstract

The invention relates to a satellite attitude control test method based on an optical sensor. The satellite attitude control test method is characterized by comprising the steps of: a) designing a high-precision guiding simulator according to a working principle of an on-satellite high-precision guiding sensor; b) controlling a galvanometer to simulate movements of an optical target on a detector;c) extracting attitude information through image processing and deviation calculation; and d) utilizing measurement information of the guiding simulator.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular to a satellite attitude control test method, especially an on-ground test method of satellite attitude control based on an optical sensor, also known as a satellite attitude control simulation system. Background technique [0002] The satellite attitude control system is the core part of the satellite system. It can keep the satellite in a specific orientation with respect to a specific reference system in space, and is the key to the stability and mission execution of the satellite. Especially astronomical observation satellites have higher requirements for satellite detection capabilities. Therefore, it is hoped that astronomical observation satellites can have higher attitude accuracy and stability. For example, the space-based multi-band Space Variable Objects Monitor (SVOM) satellite requires an attitude stability of 0.8 arcseconds / 100s. Due to the high cost of sa...
