Study confirms technical superiority of Telesat’s global low Earth orbit (LEO) satellite constellati


An independent technical study, led by members of the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology (MIT), has concluded that the design of Telesat’s global LEO constellation is far more efficient compared to those of OneWeb and SpaceX.

The study, which was presented last month at a major European space conference, evaluated the technical aspects of the three global LEO systems as described in their FCC application filings. Among the features of Telesat’s system that supported the study’s conclusions are Telesat’s high capacity satellite design, use of inter-satellite links (ISLs) and digital processors. In terms of average Gbps per satellite, the study found that Telesat’s system provides four times more capacity than the SpaceX constellation and 10 times more than OneWeb.

“Telesat has received significant industry feedback supporting the superiority of our LEO system design and this study, led by members of the Department of Aeronautics and Astronautics at MIT, further confirms the advantages of our approach,” said Erwin Hudson, Vice President, Telesat LEO. “We’re pleased with the study’s findings and excited that our procurement process working with two leading satellite industry teams – Airbus and the consortium of Thales Alenia Space and Maxar Technologies – will lead to even greater improvements in Telesat’s LEO system. We look forward to sharing these advances with our customers and the industry more broadly in the coming months.”
