Abstract A study of microwave power generation, transmission, reception and control was conducted as a part of the NASA Office of Applications* joint Lewis Research Center/Jet Propulsion Laboratory five-year program to demonstrate the feasibility of power transmission from geosynchronous orbit. This volume (1 of 4) serves as an executive summary of results concerning design approaches, estimated costs (ROM), critical technology, associated ground and orbital test programs with emphasis on de to rf conversion, transmitting antenna, phase control, mechanical systems, flight operations, ground power receiving-rectifying antenna with systems analysis and evaluation. Recommendations for early further in-depth studies complementing the technology program complete the volume. 17.
