Despite the focus on terrestrial infrastructure, satellite still plays an irreplaceable role in Inmarsat's connectivity plans. The EU-wide network of towers is girded by Europasat, a joint spacecraft between Inmarsat and Hellas Sat currently under construction by Thales Alenia Space. While Hellas Sat will own half the satellite, dubbed Hellas Sat 3, Inmarsat's Europasat will support an S-band payload for IFC. The satellite is expected to launch in 2016.
