Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency, Sagamihara), Japan Aerospace Exploration Agency (JAXA) has studied Space Solar Power Systems (SSPS) using laser and microwave beams for years since 1998. In this system, the space solar energy is converted into other optical energies in the geostationary orbit, and optical energies are transmitted to the earth without depending day and night. Therefore, this system is expected as a means to solve energy and environmental problems in the future. Critical technologies for realizing SSPS are gathering of solar light, thermal control, phased array antenna, amplifier and generator of laser, convertor from sun light to laser and assembling of large structure. Assembling of large structure on orbit is not matured technology. It is the problem how to establish this technology. In SSPS large structure of km size must be assembled on orbit. Now we study how to assemble structure of 100 m size on orbit. Various styles of large structure for SSPS were suggested until now. We try to select the best style of large structure for SSPS. This paper shows status of studies on large structure of SSPS in JAXA., 資料番号: AA0064295021}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {宇宙太陽光利用システム(SSPS)における大型構造物の検討状況}, volume = {28}, year = {2009} }
