Eutelsat contrasts the capital magnitude needed for its planned ELO nanosatellite constellation with the larger investments planned by Telesat, OneWeb, and SpaceX for broadband LEO constellations.
Encompass Digital Media executive chairman Bill Tillson estimated that Intelsat, SES, and Telesat could collectively gain $34,000,000,000 by selling C-band spectrum.
The C-Band Alliance reports that Intelsat and SES generated 90–95% of U.S. C-band revenues in 2017 while Telesat’s share amounted to a single-digit percentage.
Telesat is expected to choose soon between Airbus Defence and Space and a team formed by Maxar Technologies and Thales Alenia Space to start building its 300-satellite LEO broadband constellation.
Thales Alenia Space partnered with Maxar Technologies in competition with Airbus Defence and Space to build a megaconstellation for Canadian operator Telesat, which is seeking 300 low Earth orbit satellites.
Telesat is preparing to deploy a constellation of 298 high-throughput LEO broadband satellites designed to deliver megabits and gigabits of capacity to single locations.
The government of Canada committed a separate 600 million Canadian dollars to subsidize satellite capacity for Canadian buyers once the Telesat LEO constellation is operational.
A second Telesat prototype developed by Maxar Technologies and the University of Toronto’s Space Flight Laboratory was lost during the November 2017 Soyuz failure.
Telesat has worked with Airbus Defence and Space and a consortium formed by Maxar Technologies and Thales Alenia Space on designing the Telesat LEO constellation, with a downselect of a manufacturer expected by the end of the year.
Telesat plans to start partial service with the constellation in 2022 using around 200 satellites and to provide full service in 2023 with 300 satellites.
Telesat had a prototype satellite in orbit from Surrey Satellite Technology Limited (an Airbus company) since January 2018.
The Canadian government announced on 2019-07-24 financial support for Telesat LEO and described the constellation as a 298-satellite system intended to bring internet to some of Canada’s most rural citizens.
The government of Canada will invest 85 million Canadian dollars in the first dozen satellites of Telesat’s low Earth orbit broadband constellation as part of a research-and-development-intensive early deployment phase.
Telesat LEO is designed as a Ka-band system operating in a 1,000-kilometer orbit.
Telesat’s LEO satellites will be larger than OneWeb’s satellites, which weigh 150 kg, although Telesat has not provided an exact weight.
Telesat intends to select a satellite manufacturer by the end of 2019.
Telesat plans to spend 215 million Canadian dollars on research and development over the next five years.
Telesat plans a substantial research-and-development process using its early satellites that will be partly offset by the government’s 85 million Canadian dollar investment.
SpaceX used the same first-stage booster that launched Amos-17 to launch Telstar-19 Vantage for Telesat in July 2018 and Es’hail-2 for Es’hailSat in November 2018.
The C-Band Alliance, composed of Intelsat, SES, Eutelsat, and Telesat, proposed selling 200 megahertz of C-band spectrum primarily used for television broadcasting to companies seeking spectrum for 0.005 kg networks.
