Inmarsat’s sixth-generation (I-6) fleet will be the first to feature dual-payload satellites; each supporting L-band and Ka-band (Global Xpress) services. The I-6 satellites support a new generation of L-band capabilities, with safety services, very low cost mobile services and Internet of Things (IoT) applications.

Through the I-6’s Ka-band payload, the company will enhance coverage in regions of greatest demand.

MHI Launch Services has a rate of 97.6%. The successor to the H-IIA – the H3 Launch Vehicle – is now being developed by MHI and Japan Aerospace Exploration Agency (JAXA) and is scheduled to make its maiden flight in 2020.

Inmarsat will make a decision on its launch partner for the second I-6 satellite in due course.
