ESA developed and launched 5 European Communications Satellites between 1983 and 1988 for use by Eutelsat. The ECS system anticipated the need for digital transmission techniques for telephony, allowing for high-speed data traffic.
The ECS system has accumulated more than 3 million hours of operation.
