Inmarsat’s sixth-generation (I-6) fleet will be the first to feature dual-payload satellites; each supporting L- and Ka-band (Global Xpress) services. The I-6 satellites represent a step change in the capacity of Inmarsat’s L-band services and will support a new generation of L-band capabilities, from advanced global safety services and very low cost mobile services, to Internet of Things (IoT) applications. The Ka-band payload will add further depth to Inmarsat’s Global Xpress (GX) constellation, which began offering high-throughput broadband services worldwide in 2015. Through the I-6’s Ka-band payload, Inmarsat will augment its global coverage with greater depth of capacity in regions of greatest demand.
