A Beam Adjustment Algorithm Based on Star-Sensor Geometric Imaging Link Model with Distance Constraint

The geometric link model of integrated remote sensing imaging of star sensor and camera is proposed in order to improve the geometric positioning accuracy of remote sensing satellite image, reduce the error between satellite coordinate system and other coordinate systems, and increase the installation stability between star sensor and satellite platform. Based on the model, the beam adjustment algorithm of the star-sensing camera integrated remote sensing imaging geometric link model with additional distance constraints is proposed. The simulation results, using the initial adjustment parameters of ZY-3, show that the beam adjustment algorithm can effectively eliminate the systematic error component in the geometric positioning error and improve the geometric positioning accuracy of the remote sensing satellite image.
