The second European satellite dedicated to delivering broadband internet connections has launched.
The six-tonne Ka-Sat lifted off atop a Proton rocket from Baikonur in Kazakhstan at 0351 local time on Monday (2151 GMT on Sunday).
The flight was expected to last nine hours and 12 minutes.
The Eutelsat-operated spacecraft will concentrate its services on the estimated tens of millions of European homes in so-called "not-spots".
These are places where consumers cannot get a decent terrestrial connection.
The spacecraft follows the Hylas-1 platform into orbit. This satellite, operated by Avanti Communications of London, was launched just last month.
Ka-Sat, however, is considerably bigger, and has a notional capacity to serve up to two million households compared with Hylas's 300,000. - BBC
