Amazon is aiming to build-up its satellite business to offer internet and mobile phone services by spending $11.57bn (£8.5bn) on an acquisition of Globalstar.

The deal, announced Tuesday, will allow Amazon to get thousands of satellites into low-earth orbit through the Amazon Leo project the company has been working on for several years.

Amazon said the Globalstar takeover fits its "long-term vision for space-based connectivity" and that it will deploy a "next generation" satellite system in 2028.

By doing so, Amazon will be in closer competition with Starlink, an increasingly popular satellite-based internet and phone service company launched by Elon Musk in 2019.

Starlink has a significant head-start on Amazon's Leo, which currently only has around 200 satellites in orbit.
