空间交会对接中太阳光照窗口的研究

在空间交会对接过程中，光学测量装置对目标航天器的观测将直接受太阳光照反射强度的影响，空间交会对接必须在满足太阳光照条件的前提下进行，从正常交会对接和异常交会对接两个方面，详细分析了满足目标航天器光照条件的光照弧段和光照窗口问题，并且简要地讨论了地影区对光照弧段和光照窗口的影响，最后通过一个仿真算例，具体说明了光照条件及地影区对交会对接的约束。

Study on Sun Illumination Window during a Space Interconnection

During a space interconnection, observing the target aerocraft using optical measurement equipments is directly affected by sun illumination reflect intensity . Therefore the space interconnection must meet the sun illumination conditions. In this paper, the problems of illumination stage and illumination window which can meet the target space aerocraft illumination conditions are analyzed particularly in the two aspects: natural and abnormal space interconnection. Also it discusses the effects of earth shadow on illumination stage and illumination window briefly. In the end of the paper, it explains the restrictions of illumination conditions and earth shadow on space interconnection through a simulation example.
