Economy of modularized communication platforms and satellite clusters
Abstract
Results from an ESA cost-benefits analysis of modularized communication platforms and satellite clusters are reviewed. Attention was given to a reference satellite based on current technology, and advanced candidates for television broadcasting from a 19 deg W GEO modularized units and clusters. Both the Ariane and the Shuttle were considered as the launch vehicles for large, autonomous satellites, co-orbiting cluster units, or modular platofrms to be assembled in GEO. The analyses included development of performance and specific requirements, and cost comparison. Cost components comprised the spacecraft, constant costs, space segment costs, operations, and total system costs for a direct television broadcast system for Europe. An Ariane-launched modular platform was projected to cost 60% of the reference system, with break-even occurring at the addition of the third payload module.
