Inmarsat has appointed the market leader Boeing Satellite Systems to design and build three Inmarsat-5 satellites to operate in geosynchronous orbit, based on its proven 702HP platform. This is part of a fully-funded $1.2 billion investment programme and each satellite is expected to have a commercial life of 15 years.
The first satellite is scheduled for launch in 2013 over Europe, Middle-East, Africa and Asia. The full constellation is expected to be deployed in 2014, with global coverage planned for the end of the year.
Based on Ka-band technology, each satellite has a combination of fixed narrow spot beams that enable us to deliver higher speeds through more compact terminals; and steerable beams so additional capacity can be directed in real-time to where it's needed.
All three Inmarsat-5 satellites will be launched on Proton vehicles by International Launch Services from the Baikonur Cosmodrome in Kazakhstan. Proton is Russia's premier heavy-lift launch vehicle.
Each satellite will be served by two fully-redundant ground stations to ensure the highest levels of network availability. Inmarsat has appointed iDirect to develop the ground network and core module technology that will be integrated into satellite terminals.
