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.

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 Global Xpress users’ needs.

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