In the framework of its Earth observation program, ESA selected a set of instruments to be carried on a large satellite using the Columbus platform. An alternative scenario of three dedicated missions, based on moderate size satellites using recurring elements from ERS/SPOT, is proposed. This solution, which meets the mission objectives, provides better flexibility and resiliency with respect to financial contingency, conflicting user requirements, difficulties during development, launch, and in-orbit operations. Having a perspective of continuity, the missions will be, in the future, under the responsibility of user entities. It is therefore proposed to develop a preoperational system which will be transferred at recurring costs, after in-orbit qualification. The results of a feasibility study, including both space and ground segments, for two components (Globsat for environment and Metoc for operational meteo/oceano) are presented. Concerning the ground segment, an integrated network of stations compatible with several dedicated satellites is described.
