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:
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 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.
