APPENDIX A Supporting Data for Value of the Demonstration Satellite Used as a Power Source for Other Activities A.l Cost of Segmenting the Demonstration Satellite-CKWS The SPS demonstration satellite is constructed at LEO and then flown up to GEO. The construction requires 120 men in orbit for 15 months with 5-6 months required for blanket construction. Crews are changed every three months. It is thus necessary to transport 600 men to accomplish the construction. It is assumed that the major cost associated with segmenting the demonstration satellite is the transportation cost (Earth-GEO-Earth) for men and supplies. It is further assumed that the segmenting can be accomplished at GEO without transporting the construction facilities from LEO to GEO. The efficiency of segmentation will depend upon the size of the components/subsystems/systems that are salvaged. Since the solar blanket will be constructed in about six months it is assumed that a total of 240 man-trips will be required to segment the power supply. Therefore: . Transportation cost for 240 men plus supplies d= 335,000 KW Trans. Cost = Cost from Earth to LEO + Cost from LEO to GEO • Unit Cost of POTV = 63 X 10^6$ • Design Life of POTV = 300 flights • Cost per POTV Flight = .09 X 106$ • No. of People/POTV Flight = 48 • Number of HLLV Flights/POTV Flight = 3 • Unit Cost of HLLV = 611 X 106$ • Design Life of HLLV = 300 flights
