Laser beamed power - Satellite demonstration applications

Abstract

Feasibility of using a ground-based laser to beam light to the solar arrays of orbiting satellites to a level sufficient to provide the operating power required is discussed. An example case of a GEO communications satellite near the end of life due to radiation damage of the solar arrays or battery failure is considered. It is concluded that the commercial satellite industry should be able to reap significant economic benefits through the use of power beaming which is capable of providing supplemental power for satellites with failing arrays, or primary power for failed batteries.
