In August 2010 Inmarsat awarded Boeing a contract to build a constellation of three Inmarsat-5 satellites, as part of a US$1.2 billion worldwide wireless broadband network called Inmarsat Global Xpress. The three Inmarsat-5 (I-5) satellites will be based on Boeing’s 702HP spacecraft platform. The first is scheduled for completion in 2013, with full global coverage expected by the end of 2014. The satellites will operate at Ka-band in the range of 20–30 GHz. Each Inmarsat-5 will carry a payload of 89 small Ka-band beams which combined will offer global Ka-band spot coverage. In addition each satellite will carry six fully steerable beams that can be pointed at commercial or government traffic hotspots. According to Inmarsat, Global Xpress will deliver download speeds in excess of 60Mbit/s to a 60 cm dish. As a result of Global Xpress wide coverage satellites’ bandwidth of only 12Gbit/s each will be moderate compared to Ka band satellites with a narrower footprint.
There are plans to offer high-speed inflight broadband on airliners through Global Xpress.
