The EUTELSAT I series was developed by ESA (the European
Space Agency) as part of the ECS (European Communications Satellite)
programme. Once launched and checked out in orbit each satellite
was handed to EUTELSAT for commercial operations. The satellites
are maintained in orbit by ESA from its Redu earth station in
Belgium. Four EUTELSAT I satellites were successfully launched
between 1983-88. EUTELSAT I-F1, F4 and F5 are still operating. |
