Solar power satellites (s.p.s.) now in the research and development stage are intended to be placed in geostationary orbits where large arrays of photocells will collect solar energy which will be delivered to Earth on a frequency of 2.45 GHz at a power level of 10 GW. The calculations in this paper indicate that severe restrictions will be placed on the use of radio telescopes on Earth for the study of radio emissions from celestial objects. For a single s.p.s. it would be possible to operate with the radio receiver protected by suitable filters at radio frequencies well separated from 2.45 GHz and at angles of look well displaced from the s.p.s. However, operational systems involving many s.p.s. to supply significant amounts of power to Earth would create serious hazards to radio-astronomical research, except possibly in thinly populated areas of the Earth.
