The invention provides a satellite configuration suitable for configuring a large-aperture optical camera and needing on-orbit rapid maneuvering. The satellite configuration comprises a service module, a load module, a camera light shield, a two-module locking mechanism and a solar cell array. The service module adopts an outer hexagonal and inner hollow structure, and the outer hexagon fully utilizes the available envelope of the carrying fairing to provide a larger installation space for the whole satellite, so that the height of the service module is reduced, and the overall center of mass of the satellite is reduced; the inner circular hollow part provides an installation space for the camera secondary mirror support cylinder and the camera light shield. The load cabin is located below the service cabin when the satellite is vertically parked, and the camera secondary mirror supporting cylinder penetrates through the service cabin and provides an installation interface for the carrying separation device. The two-cabin locking mechanism provides mechanical support for the service cabin. The solar cell arrays are symmetrically arranged on the two sides of the service module. The problem that the inertia of the whole satellite is too large is solved, the requirement for in-orbit rapid maneuvering of the large-aperture optical satellite is met, and the method has the advantage that the mechanical environment and the space thermal environment of the load active section are improved.

    本发明提供一种适用于配置大口径光学相机及需要在轨快速机动的卫星构型,包括服务舱、载荷舱、相机遮光罩、两舱锁定机构和太阳电池阵。服务舱采用外六边形内中空构型,外六边形充分利用运载整流罩可用包络,为整星提供更大的安装空间,进而降低服务舱高度,降低卫星整体质心;内圆形中空为相机次镜支撑筒和相机遮光罩提供安装空间。载荷舱在卫星竖直停放下处于服务舱的下方,相机次镜支撑筒贯穿服务舱,为与运载分离装置提供安装接口。两舱锁定机构为服务舱提供力学支撑。太阳电池阵对称设置在服务舱的两侧。本发明解决了整星惯量过大的问题,满足了大口径光学卫星在轨快速机动的需求,具有改善载荷主动段力学环境以及空间热环境的特点。
