In order to reduce the transportation cost in SSPS program, it is important to increase the payload ratio of OTVs so that the transportation requirement for reusable launch vehicles is decreased. In this study, it was suggested that hundreds of OTVs carry the materials separately and SSPS is assembled on geostationary earth orbit. Estimation results indicated that the payload ratios of OTVs were approximately 0.5 in the four cases with types of electric and thermal thrusters used. Mass breakdowns of the OTVs were also shown in the four cases. In addition, an image of the OTV with ion engines was illustrated using several practical parameters., 資料番号: AA0048129008, レポート番号: JAXA-RM-04-011}, title = {宇宙太陽発電システム軌道間輸送技術の検討}, year = {2004} }
