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

Abstract

  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.
