The invention discloses a low-temperature optical
satellite configuration suitable for a great elliptic frozen
orbit complex light condition. The low-temperature optical
satellite configuration comprises a platform and an auxiliary cabin, wherein the platform is in charge of bearing most of stand-alone equipment in the
satellite, and divided into an upper cabin section and a lower cabin section; the auxiliary cabin is mounted on a top plate of the platform and in a cubic shape to carry antennas required by
satellite data transmission, measurement and control, satellite-to-satellite communication and other antennas required over the ground; a cross section of the platform is in a rectangular sealed
hexahedron; the upper cabin section is formed by a top plate, six side plates, four upper separation frames and layer plates; and the lower cabin section is formed by a base plate, six side plates, fourth lower separation frames and layer plates. By the use of the low-temperature, a stable and great-area nightside surface can be guaranteed upon the complex light conditions of the great elliptic frozen
orbit, and imaging temperature environment demands for a low-temperature optical cameracan be guaranteed; a great over-the ground area can be provided, so ground load
layout space
utilization rate can be ensured; great specific stiffness and
specific strength can be provided; and when astorage case is flatly placed, the whole satellite
centroid deviation range can be well controlled.
