「宇宙太陽発電システムの検討現状と進め方提案」

太陽発電衛星（SPS)は，システムが極めて巨大であるため，一般に理解されにくい．その一因は，システムの構成と機能が未だ示されないことにある．本論文では，SPSの所要技術を概観し，特にシステム開発の岐路となる衛星姿勢制御とスリップリング，および巨大アンテナ技術の検討現状を示す．次にこれまで検討されてきた諸システムモデルの課題を明らかにして，あわせて段階的な開発手法を提案する．

"Current Status of a Space Solar Power System Study and its Program Proposal"

A solar power satellite (SPS) is hard to be understood by the public due to its extremely large system scale. One of the reasons is that the constitution and function of the system is not clarified yet. This paper surveys the necessary technologies first. Especially, satellite attitude control and a relevant slip ring that indicate the crossroads of system development, and a huge antenna technology are presented. Next, several system models studied so for are introduced. The stepwise scenario of development will be proposed.
