In this concept, the solar power satellite system consists of sunlight reflectors and an Earth-pointing segment. The Earth-pointing segment is on a common GEO, and the reflectors are placed on the north and south by using solar pressure to raise their orbits from GEO. Therefore, the orbits of the reflectors and that of the Earth-pointing segment make three parallel GEOs. The feasibility is also discussed focusing on the orbital and attitude mechanics of the reflector. Through some analyses, it is shown that the required propellant for the control of the formation flying SPS is about a few 10 percent larger than that for previous concepts. The structural feasibility is also discussed through FEM analyses. It is revealed that it is possible to assemble the lightweight reflector structure with sufficient stiffness using deployable structures based on current technologies. Although FF-SPS requires more control propellant than previous concepts, its feasibility is technologically equivalent to previous ones. FF-SPS is the first concept that has both Earth-pointing and Sun-pointing segments without any single point of failure., 資料番号: AA0048129002, レポート番号: JAXA-RM-04-011}, title = {宇宙エネルギー利用システムの研究:フォーメーションフライトにより構成されるSSPS}, year = {2004} }
