Inmarsat is a British-based provider of global mobile satellite communications. Their Global Xpress (GX) constellation is the world’s first globally available, broadband connectivity service and was created to enable communities across the world to benefit from the emerging digital society.

Following satellite separation at 19:53 ET, Inmarsat acquired telemetry from their Perth ground station at 20:04 ET. The launch team from Inmarsat and Boeing Network & Space Systems, the manufacturer of I-5 F4, are now raising the spacecraft to a geostationary orbit, at which point the satellite will deploy its solar arrays and reflectors, and undergo payload testing.
