Requirements for a multidisciplinary earth observation satellite system in geosynchronous orbit were analyzed. A methodology for selection of candidate missions is presented taking into account the particular characteristics of geosynchronous orbits for observation of transient phenomena on the earth and ocean surface and in the atmosphere. The conceptual design of the payload and the spacecraft features modularity and flexibility. It includes a preliminary design of a one meter Ritchey-Chretien optical telescope as main instrument on a satellite which could be launched by Ariane into a geostationary orbit. The preferred concept allows exchange of focal plane elements to permit the performance of different kinds of measurement from high resolution imaging to vertical sounding. The preferred satellite concept is based on a three axis stabilized spacecraft. Particular attention was given to investigation of the attitude measurement and control subsystem necessary to achieve the extreme performance requirements compatible with high resolution imaging of the earth from geostationary orbit.
