Abstract A study of microwave power generation, transmission, reception and control was conducted as a part of the NASA Office of Applications1 joint Lewis Research Center/Jet Propulsion Laboratory five-year program to demonstrate the feasibility of power transmission from geosynchronous orbit. This volume (3 of 4) summarizes the efforts and presents recommendations associated with preliminary design and concept definition for mechanical systems and flight operations. Technical discussion in the areas of mission analysis, antenna structural concept, configuration analysis, assembly and packaging with associated costs are presented. Technology issues for the control system, structural system, thermal system and assembly including cost and man’s role in assembly and maintenance are identified. Background and desired outputs for future efforts are discussed. 17. Key Words (Suggested by Author(s)) Microwave power transmission; power from space; satellite power transmission; phased array power transmission; rectifying antenna (rectenna). 18.
