It was originally built as Orion 2 for Orion Network Systems. This was later cancelled when Orion merged with Loral Skynet, who opted to procure satellites from their sister company, Space Systems Loral. It was subsequently sold to Eutelsat as a backup satellite and designated RESSAT. It was subsequently launched in place of the original Eutelsat W1, which was damaged whilst under construction and eventually launched as Eutelsat W5.[1]
Following its launch and on-orbit testing, it was placed in geostationary orbit at 10° East, from where it provided broadcast and communications services to Europe using wide-band feeds. In June 2009, it was moved to 4° East,[2] and redesignated Eurobird 4A. It carries twenty eight transponders, and has an expected on-orbit lifespan of 12 years.
