Technical solutions for cost effective implementation and management of the space segment of a European telecommunication network for the 1990's were compared. The most promising concept is an Ariane launched modular platform where the program cost could be lowered to 44% (depriciation rate 0 %) of a reference system with a conventional concept and design. A cost advantage of a cluster type concept is not observed. Comparing individual satellite systems with modular assembly concepts (with a sharing of the service functional bus system) the cost break even point is reached after the third payload module is docked to the central service modules. High system reliability requirements could be covered after the attachment of the second transfer orbit docking system to the service module satellite. Potential benefits of a European satellite assembly system are high due to its modular approach and the inherent high service bus system reliability. The GEO-assembly approach shows high mission flexibility and could provide a good payload adaptability to varying demands, and soft system start-up cost.
