Eutelsat W1 → Eurobird 4A → Eutelsat 4A

Eutelsat W1 [Astrium]

Originally ordered by Orion Network Systems as Orion 2, the contract was later terminated. It was then bought by Eutelsat as spare satellite, called RESSAT, which was later renamed Eutelsat W1 as a replacement satellite compatible with their previously-launched W2 and W3 spacecraft. Eutelsat subsequently decided to launch W1 in September 2000. Located at the 10 degrees East position, the satellite serves a full range of applications that include that include business communications, Internet-based services and television transmission. It has 28 channels, 20 of which provide coverage of Europe, North Africa, the Middle East and central Asia via a fixed widebeam, with the remaining eight connected to a steerable spotbeam, to address new markets in geographical areas outside the widebeam coverage area (notably southern Africa). Services can be simultaneously provided within both coverages.

Prime contractor for the satellite, Astrium supplied both the platform (based on the Eurostar-2000+ version of the company's Eurostar series) and the payload.

In December 2011 Eutelsat announced, that their satellite assets will be renamed under a unified brand name effective from March 2012. This satellite became Eutelsat 4A.
