Arianespace announces Inmarsat launch contract

Arianespace has signed a launch contract for Inmarsat’s fifth Global Xpress very high throughput communications satellite.

Arianespace and Inmarsat have announced the signature of the launch contract for Inmarsat’s fifth Global Xpress very high throughput communications satellite (GX-5).

The satellite will be orbited by an Ariane 5 heavy-lift launcher from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana (South America) during the second half of 2019.

GX-5 will offer services covering the Middle East, Europe and the Indian sub-continent. The payload will be fully integrated into Inmarsat’s current GX high-speed network.

Inmarsat’s GX-5 satellite is based on Thales Alenia Space’s upgraded Spacebus 4000 B2 platform.

GX-5 features a design life of 16 years and will weigh about four metric tons at launch, with a payload rated at approximately 6.8kW of electrical power. It will be Ariane's tenth Inmarsat payload, following Inmarsat S EAN in June.
