为提供GEO卫星星蚀的起止时间,精确预报卫星能源分系统状态切换时间,以利于卫星在轨安全管理,提出了一种新的星蚀计算方法。不仅能准确预报星蚀起止时间、星蚀类型,而且可精确预报能源分系统状态切换时间。算法已成功地用于实际卫星管理。 In order to provide the starting and ending time of GEO satellite eclipse and accurately forecast the state switching time of satellite energy subsystem, in order to facilitate satellite orbit safety management, a new method of calculating eclipse is proposed. Not only can accurately predict the onset and ending time of the solar eclipse, the type of solar eclipse, but also accurately forecast the energy subsystem state switching time. The algorithm has been successfully used for actual satellite management.
