“…While a nominal atmospheric attenuation of 978-1-4799-1622-1/14/$31.00 c 2014 IEEE. about 2% for a microwave frequency of 2.45 Ghz [1] is comparably small, yet 100 MW of power is absorbed by the atmosphere in the case of a 5 GW power station in geostationary orbit (GEO). Even though substantial amounts of energy are expected to be deposited in the atmosphere by utility-scale SSP satellites, only little information is available about atmospheric interactions of microwave power beams.…”

Abstract-In the most common space solar power (SSP) system architectures, solar energy harvested by large satellites in geostationary orbit is transmitted to Earth via microwave radiation. Currently, only limited information about the interactions of microwave beams with energy densities of several tens to hundreds of W/m 2 with the different layers of the atmosphere is available. Governmental bodies will likely require detailed investigations of safety and atmospheric effects of microwave power beams before issuing launch licenses for SSP satellite systems. This paper proposes to collect representative and comprehensive data of the interaction of power beams with the atmosphere by extending the infrastructure of the High Frequency Active Auroral Research Program (HAARP) facility in Alaska, USA. Estimates of the transmission infrastructure performance as well as measurement devices and scientific capabilities of possible upgrade scenarios will be discussed. The proposed upgrade of the HAARP facility is expected to deliver a wealth of data and information which could serve as a decision base for governmental launch licensing of SSP satellites, and which can be used in addition to deepen public acceptance of SSP as a large-scale renewable energy source.
