s, having at least 12 satellites in each plane. The siting of the orbital planes is to comply with the Canadian government's Enhanced Satellite Constellation Project, as well as providing global coverage. The constellation is officially named Telesat Lightspeed. In 2017, Telesat expanded the LEO constellation plan to about 300 satellites, coupled with 50 ground stations across the globe. There would be about 80 polar orbit satellites, with the remainder in inclined orbits, for global coverage, including polar regions. The internet satellite constellation is targeted to have a 30-50 ms latency. The satellites are expected to be around and last 10 years on orbit. The constellation is expected to have a 16-24 Tb/s capacity with 8 Tbit/s (1 TB/s) available for customers. In 2018, the Phase 1 pathfinder test satellite for the LEO constellation was launched. Various customers and satellite transceiver equipment manufacturers started testing with the satellite. In 2019, Telesat contracted with
