GEO space platform economics - Impact of concept, size, launch mode and lifetime

The design of GEO communications platforms is examined from an economic perspective. The historical and projected growth of satellite services and spacecraft mass and capability is traced, and the concepts proposed for large conventional satellites, platforms with integrated transfer propulsion, modular platform assemblies, and large man-tended stations with service and repair are reviewed. Spacecraft and launch costs are evaluated, taking the impact of design lifetime into account. A decrease in per-channel space-segment costs is predicted for larger satellites and platforms. Graphs and tables of the numerical results and drawings of proposed systems are included.
