The EUTELSAT I series of satellites was developed by the European Space Agency (ESA) as part of the European Communications Satellite (ECS) program. Once launched and checked out in a geostationary orbit over Europe, each satellite was handed to EUTELSAT for commercial operations. Four EUTELSAT I satellites were successfully launched between 1983-1988. They served both public and private traffic, including telephone services, fax, data, land mobile service, and television and radio programming. Each had a design life of 7 years and a bandwidth of 72 MHz.
