1.1.6 The Boeing SPS-Concept 1977/78 Ground Power Output Total Mass Conversion Efficiency without CR Microwave Generator Type Generator Efficiency System Efficiency Total Cost (Without DDT&E) Electricity Cost Characteristics: Eight major pieces would be assembled in a huge LEO construction base and then shipped by electric self-propulsion to GEO. In Geo the eight modules would be integrated to the SPS with the help of a final construction base. In the operational phase each of the two microwave antennas would deliver 5 GW to a ground based rectenna. The construction philosophy is based on a general simplicity of all satellite parts.
