Power beaming providing a space power infrastructure

A study based on two levels of technology maturity, which applies to the power beaming concept to four planned satellite constellations, is described. The analysis shows that with currently available technology, power beaming can provide mass savings to constellations to orbits ranging from low-Earth orbit to geosynchronous orbit. Two constellations, a space surveillance and tracking system and space-based radar, can be supported with current technology. The other two constellations, a space-based laser array and a boost surveillance and tracking system, will require power and transmission system improvements before their break-even specific mass is achieved. A doubling of SP-100 conversion efficiency from 10 to 20% would meet or exceed break-even for these constellations.<>
