The EAN payload is part of a "condosat" constructed by Thales Alenia Space, which incorporates a second payload for Hellas-Sat and is scheduled to be launched from the Guiana Space Centre in Kourou, French Guiana in mid-2017.
The condosat was originally scheduled for launch with SpaceX but a delay in SpaceX’s launch schedule resulted in the condosat to be moved to an Arianespace launch.
Inmarsat will now launch Inmarsat-5 F4, a Global Xpress (GX) satellite, with SpaceX, with the launch planned for the first half of 2017. The company says it is looking forward to continuing to work with SpaceX.
"This launch schedule supports the introduction of our ground-breaking integrated satellite and air-to-ground network, developed by Inmarsat and Deutsche Telekom, which will deliver a very high capacity broadband Wi-Fi experience for passengers flying throughout Europe.”
