The invention discloses a geostationary orbit satellite midnight sunlight avoidance method giving consideration to effective imaging, which not only can ensure that sunlight does not enter a beveled light shield, but also can ensure that the imaging quality of a satellite camera meets service requirements during midnight sunlight avoidance, reduces the single-day detection blind time of a satellite to a minute level, and improves the detection efficiency. And meanwhile, the midnight sunlight avoids the camera optical axis and automatically recovers to point to the earth center. Three evasion strategies are designed according to the change of the included angle between the sun vector and the satellite orbit plane in one year, the evasion trajectory is optimized, and the coverage degree of a key observation area is improved.
本发明公开了一种兼顾有效成像的静止轨道卫星午夜阳光规避方法,不仅能保证阳光不会入射进斜切式遮光罩,而且可以保证午夜阳光规避期间卫星相机的成像质量满足业务要求,缩减卫星单日探测盲时至分钟级,同时午夜阳光规避前后相机光轴自主恢复指向地心。根据一年之中太阳矢量与卫星轨道平面的夹角的变化,共设计了三种规避策略,优化规避轨迹,提高对重点观测区域的覆盖程度。
