Blue Origin, the rocket company owned by Amazon founder Jeff Bezos, says it will launch more than 5,400 satellites to create a new communications network.
Named TeraWave, it will offer continuous internet access around the world, with the ability to move large amounts of data much more quickly than rival services.
But even after launching thousands of satellites, Blue Origin would still have far fewer in orbit than Elon Musk's Starlink, which currently dominates the satellite internet market.
Starlink - part of Musk's rocket firm SpaceX - also offers internet and phone services to individual customers, while Blue Origin says TeraWave will be focused on data centres, businesses and governments.
Blue Origin said its network, at its fastest, would allow upload and download speeds of as much as 6 terabits per second, much faster than rival commercial satellite services currently offer.
