Global Xpress

A global mobile broadband revolution

Global Xpress (GX) has been delivering seamless, high-speed broadband connectivity all around the world since December 2015.

The GX constellation is now made up of four Ka-band, high-speed mobile broadband communications satellites, following the launch of Inmarsat-5 F4. Each I-5 satellite is expected to have a commercial life of 15 years.

The first three I-5 satellites were launched from the Baikonur Cosmodrome in Kazakhstan, and together they provide the coverage required to deliver global GX services:

  • I-5 F1 – launched on 6 December 2013 to serve Europe, the Middle East, Africa and Asia
  • I-5 F2 – launched on 1 February 2015 to serve the Americas and the Atlantic Ocean Region
  • I-5 F3 – launched on 28 August 2015 to serve the Pacific Ocean Region.

As part of Inmarsat’s US$1.6 billion programme commitment, the fourth Global Xpress satellite (I-5 F4) was launched from Cape Canaveral in Florida, USA on 15 May 2017 to provide additional capacity. It will become operational later in 2017.

First global Ka-band commercial satellite service

The I-5 satellites operate with a combination of fixed narrow spot beams that enable Inmarsat to deliver higher speeds through more compact terminals, plus steerable beams so additional capacity can be directed in real-time to where it’s needed.

Operating in the resilient Ka-band, while integrating seamlessly with our proven L-band network, GX allows customers across aviation, maritime, enterprise and government sectors to have reliable and assured access to high-throughput communications.

With Cisco, we have also developed the Inmarsat Gateway to deliver a whole new world of innovative, content-rich applications – developed by our Certified Application Partners – tailored to meet GX users’ needs.

Global Xpress represents an important step in Inmarsat’s transformation from a satellite operator to a digital services enabler. Ever innovative, we are going beyond connectivity to power the emerging global digital society. From smart shipping and smart cities to connected aircraft and connected cars, we will provide the best networks and the best solutions to shape the new digital world.
