摘　　要：以水平圆编队构型为例，利用卫星防真工具包（STK）工具构建两种三颗星绕主星伴飞的编队飞行模型。在Matlab软件中读取从STK编队模型导出的轨道数据，包括光照时间、太阳相位角、伴飞星之间的位置关系以及太阳、月亮分别与观测相机之间的位置关系等，并建立伴飞星对主星、伴飞星之间进行天基光学观测的可见性分析模型，推导出伴飞星对主星、伴飞星之间可见性时段。综合考虑实际空间环境中的各个影响因素，提出了编队卫星在轨运行时做可见性分析的方法，得出了对在轨目标进行天基光学观测的可见性分析结果，为编队星座技术应用于天基光学观测提供了技术支撑。Take example for horizontal round formation configuration, the formation flying model that three satellites flying around a main satellite is designed by satellite tool kit （STK） software. The correlative orbital data from the formation flying model in STK are acquired by the project set up in Matlab, including lighting time, sun phase angle, the position relation between formation flying satellites, the position relation among sun, moon and sensor. A visibility analyses model between formation flying satellites or formation flying satellite and main satellite are found in Matlab. Finally, the visibility time periods between formation flying satellites and one of formation flying satellites to main satellite are summed up. Kinds of factors are consindered in formation flying satellite models in STK and a method which analyzes the orbital formation flying target＇s visibility is put forward. The visibility analytical result of doing space-based optical observation to orbital target is achieved, which provides a technical sustentation for formation flying satellite constellation applying to space-based optical observation.
