Origin:Proc SPS 91 Power from Space Symposium, Electricite de France

SUMMARY - The construction of a near-term solar power satellite (SPS) has been proposed, in the form of a satellite in equatorial low Earth orbit transmitting up to 10 Mw of radio-frequency (rf) power at 2.45 GHz, with the objective of demonstrating the generation of useful electric power on Earth using available space technologies and launch services. This paper examines the main factors that must be considered in the design of the ground segment (i.e. the rectennas and related power-conditioning equipment) for such a system, which will become important research facilities, of interest to electric utilities in every county.
