Description

technical field [0001] The patent of the present invention belongs to the technical field of cube satellites, and is a highly integrated three-unit cube satellite with maneuverable orbit change. Background technique [0002] CubeSat refers to a nanosatellite composed of one or more standard units (called 1U (one unit)) with a size of 10cm×10cm×10cm. Usually the launch runs in a low earth orbit of about 500-1000km. Compared with traditional large satellites, they have the characteristics of small size, light weight, good performance, rapid response, short development cycle, low cost, formation and networking, and reconfigurable functions. With the development of CubeSat technology, it has been able to partially undertake the tasks of large satellites, and its applications in communications, military affairs, remote sensing of the earth, deep space exploration, meteorological services, scientific research and technical experiments have grown rapidly, and are receiving more an...
