The SpaceX company has begun the roll-out of its orbiting broadband system, the BBC reports.
A Falcon-9 rocket launched from Cape Canaveral in Florida late on Thursday, packed with 60 satellites capable of giving users on the ground high-speed connections to the internet.
Entrepreneur Elon Musk's firm aims eventually to loft nearly 12,000 spacecraft for its "Starlink" network.
The Falcon lifted off from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station at 22:30 local time (02:30 GMT, Friday).
Deployment of the Starlink satellites was successfully completed just over an hour into the flight, SpaceX announced.
