British-based firm OneWeb has launched 34 satellites into orbit from a cosmodrome in Kazakhstan, expanding its in-orbit constellation to 322 satellites.

The satellites lifted off from Kazakhstan’s Baikonur cosmodrome at 1807 GMT on Tuesday.

OneWeb plans to launch a total of 648 low earth orbit satellites to roll out a high-speed global internet connection including to the most remote corners of the world.

The launch, carried out by Arianespace, keeps OneWeb on track to start a service in swathes of the northern hemisphere this year and to deliver a global service next year.

OneWeb resumed satellite launches in December after emerging from bankruptcy protection with $1 billion in equity investment from a consortium of the British government and India’s Bharti Enterprises.

OneWeb has received further financing from Bharti Enterprises as well as investment from Eutelsat Communications and Japan’s Softbank.
