Abstract
Remote sensing satellites are usually deployed on sun-synchronous orbit,and the control of their attitudes is complicated.Satellite can adopt attitude side-looking to expand the detection range of imaging load,and eliminate or compensate imaging distortion by attitude yaw-steering.The attitude maneuver of the above two modes has a great influence on the sun illumination angle,which makes the illumination angle of solar array of satellites vary greatly at different times of the year,which has a great influence on the design of satellite power supply system.In this paper,the factors of the satellite attitude and solar array layout are decomposed and considered respectively,and by coordinate conversion,sunlight vector and normal of solar array are mapped to the same coordinate to solve the sun illumination angle.Simulation results show that the proposed calculation method for the analysis of sun illumination angle is feasible.关键词
