A key element in the overall feasibility of the Satellite Power System (SPS) is the transportation concept either available or projected to be available in the time being considered. Since transportation costs contribute significantly to the total SPS life cycle cost, methods of reducing transportation cost or simplifying transportation operations greatly enhance the acceptance of the SPS concept. Major elements of the SPS transportation system consist of heavy lift launch vehicle (HLLV), Space Shuttle, cargo and personnel orbit transfer vehicles (COIV and POTV), and on-orbit mobility system (OOTV). A major driver in transportation system selection is the COTV concept used for transfer from low earth orbit (LEO) to geosynchronous equatorial orbit (GEO). Depending on COTV concept selection, two of every three launch vehicle flights to LEO may be required for OTV propellant resupply. Trade studies were conducted on SPS construction site (LEO or GEO) and COTV concepts (chemical, nuclear and electric self-powered or dedicated). (Kursetz)
