Current Status of a Space Solar Power System Study and Future Study Points

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 far are ntroduced. The stepwise scenario of development will be proposed.
