Our fleet
The award-winning Inmarsat-4 (I-4) satellites are the pride of our fleet. Sixty times more powerful than their predecessors, the I-3 series, they set a new benchmark for mobile satcoms, establishing the world’s first global 3G network and delivering our portfolio of broadband services.

Our network
Our fleet of spacecraft provides mobile and fixed communications anywhere in the world. The satellites are linked to the terrestrial telecom network via a series of ground-based satellite access stations around the globe that connect users to the internet and route their telephone calls.
-
Our coverage
Inmarsat’s satellites transmit radio waves that cover the entire planet, apart from the extreme poles. They are positioned in geosynchronous orbit in such a way that their beams form seven overlapping regions, providing seamless coverage from latitudes -82 to +82 degrees.

Global Xpress®
A new constellation of Ka-band satellites, the Inmarsat-5s, is being built by US manufacturer Boeing for launch in 2013-14. They will form the backbone of our new Inmarsat Global Xpress network, offering broadband speeds of up to 50Mbps around the world.
Our satellites
We launched the world’s first global mobile satellite communications system to enable merchant ships to stay in touch or call for help in an emergency.
Today we own and operate three global constellations of 10 satellites flying in geostationary orbit 37,786 km (22,240 miles) above the Earth. And we remain a pioneer in space communications and the industry leader with the planned launch of four powerful new spacecraft in 2013-14.
