LEO constellation
Telesat plant constellation of communication satellites in low earth orbit (engl. Low Earth Orbit LEO), similar to the Starlink system of SpaceX , but much smaller, about 300 satellite. A first test satellite names LEO Vantage 1 was established in January 2018 a Rideshare -Flight on an Indian PSLV launch rocket. With the commissioning of this satellite, Telesat secured the radio frequencies already reserved for the planned satellite network.
also the operation of aConstruction of the actual constellation is slated to begin with the launch of 78 satellites into polar orbits in 2022. In the same year, it should be possible to use the system in high northern latitudes . 200 more satellites should enable a global offer from 2023 . Telesat signed contracts with the US companies Blue Origin and Relativity Space for several launches each with the New Glenn and Terran 1 rockets, which are still in development .
