Canada’s Telesat is racing to launch a low-earth-orbit (LEO) satellite constellation to provide high-speed global broadband from space, pitting the satellite communications firm founded in 1969 against two trailblazing billionaires, Elon Musk and Jeff Bezos.

Musk, the Tesla Inc CEO who was only a year old when Telesat launched its first satellite, is putting the so-called Starlink LEO into orbit with his company SpaceX, and Amazon.com Inc, which Bezos founded, is planning a LEO called Project Kuiper. Bezos also owns Blue Origin, which builds rockets.

Despite the competition, Dan Goldberg, Telesat’s chief executive officer, voices confidence when he calls Telesat’s LEO constellation “the Holy Grail” for his shareholders - “a sustainable competitive advantage in global broadband delivery.”
