Global Xpress

Global commercial service achieved

Global commercial service introduction (CSI) was achieved for Global Xpress (GX) during December 2015.

The GX constellation is formed of three Ka-band, high-speed mobile broadband communications satellites. Each I-5 satellite is expected to have a commercial life of 15 years and together, the three satellites provide the coverage required to deliver global GX services.

Each satellite was launched from the Baikonur Cosmodrome in Kazakhstan:

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

As part of Inmarsat’s US$1.6 billion programme commitment, a fourth Global Xpress satellite (I-5 F4) is currently completing construction and testing by Boeing in California, and is likely to be launched in the second half of 2016 in order to provide additional GX capacity.

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 Service Enablement Platform (ISEP) and the Inmarsat Gateway, which will deliver a whole new world of innovative, content-rich applications – developed by our Certified Application Partners – tailored to meet GX users’ needs.

During the course of 2016, Inmarsat will be introducing a series of market-specific, high-speed connectivity services powered by Global Xpress.
