A British-based company is to launch a huge satellite into space, improving mobile broadband services around the world.

The launch of the satellite, said to weigh over six tonnes, will take place from Kazakhstan.

InMarsat has carried out a £722 million programme designed to increase its broadband coverage over the globe, reports the Press Association.

According to the news agency, an InMarsat spokesman commented: "The Proton M will carry the Inmarsat-4 F3 into geostationary orbit at 22,240 miles.

"Together with its two sister satellites, already in orbit, the completed constellation will deliver full and seamless global coverage for our entire range of broadband mobile satellite services."

InMarsat mobile Bgan terminals are being used by many media organisations in the process of relaying coverage of the 2008 Olympic Games from Beijing.
