Embodiment Construction
[0020] For the star sensor involved in the embodiment of the present invention, please refer to the article "Integrated Small Star Sensor" in the 2002 issue of "Aerospace Control", and for the static star simulator involved, please refer to China Aerospace Publishing House 2003 Published "Missile and Aerospace Series-Satellite Control System Simulation Technology" edited by Liu Liangdong.
[0021] First define the star sensor measuring coordinate system and the positive and negative directions of the star sensor's rotation angle. The definition method of the star sensor measuring coordinate system is: taking the centroid of the star sensor as the origin of the star sensor measuring coordinate system; taking the vector passing through the origin, perpendicular to the bottom surface of the installation and pointing to the outer space of the star sensor as the measuring coordinate system + Y axis; the vector passing through the origin, parallel to the optical axis of the star sensor ...
