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.
