Inmarsat expects to have three new satellites [I6-F1,I6-F2,GX-5] in orbit by 2021. None have yet been assigned to launchers. ...Inmarsat executives have said that Qatar Airways’ commitment to equip 130 aircraft with GX inflight connectivity hardware was a strong motive for the operator to invest in GX-5. Pearce said Inmarsat-5 F4 will support inflight connectivity demand over Europe until GX-5 arrives in 2019. After that, Inmarsat-5 F4 will probably shift to Asia, he said.
