Telesat,formerlyTelesat Canada,is a Canadiansatellite communicationscompanyfounded on May 2, 1969. The company isheadquarteredinOttawa.

History

[edit]

Telesat began in 1969 as Telesat Canada, a CanadianCrown corporationcreated by an Act of Parliament.[1]Telesat Canada launchedAnik A1in 1972 as the world's first domestic communications satellite ingeostationary orbitoperated by a commercial company;[2]this satellite was retired from use in 1981.[citation needed]Until February 1979, Telesat had a legal monopoly onEarth stationsin Canada: any entity wishing to send or receive satellite signals had to sign a long-term lease with Telesat Canada for anEarth station.[citation needed]Contracts for such leases were still enforced after the monopoly was ended.[citation needed]

Telesat Canada was privatized and sold by the federal government toBell Canadain 1998.[3]

On December 18, 2006,Loral Space & Communicationsannounced that it, along with Canada'sPublic Sector Pension Investment Board(PSP Investments), would acquire Telesat for US$2.8 billion.[4]On October 5, 2007, they received the final regulatory approval necessary to complete the acquisition of Telesat fromBCE Inc.(the new holding company for Bell) for CAD$3.25 billion. The acquisition closed on October 31, 2007, with Loral owning 63% of Telesat.[5]

At the same time, Telesat merged with Loral Skynet (formerly AT&T Skynet), a subsidiary of Loral Space & Communications. Loral Skynet was a full-service global satellite operator headquartered inBedminster, New Jersey.This resulted in the transfer of all of the assets of Loral Skynet to Telesat.

Telesat announced on December 30, 2009, thatNimiq 6was built bySpace Systems/Loral(SS/L).Bell Satellite TV,a Canadian satellite TV provider agreed to fully lease the satellite for its lifetime to serve their subscribers across Canada. Nimiq 6 has a payload of 32 high-poweredKu-bandtransponders. It uses the SS/L1300 platform and has a 15-year mission life. It was launched in 2012 byInternational Launch Services(ILS).[6]

On November 17, 2010: Telesat Holdings Inc. hiredJPMorgan Chase& Co.,Morgan StanleyandCredit SuisseGroup AG to start a formal sales process and offer so-calledstaple financingto interest buyers for $6 billion to $7 billion.[7]

MHI Launch Services (formerly H-IIA Launch Services)[8]) launched Telstar 12 VANTAGE for Telesat in November 2015 on a H2A204 variant of theH-IIArocket,[9]and it commenced service in December 2015.[10]

Lightspeed LEO constellation

[edit]

In 2016 Telesat announced it would launch alow-Earth-orbit(LEO)constellationof 120 satellites, inpolar orbitand ininclined orbits,about 1,000 km (620 mi) in altitude. The satellites would use theKa-band,across 6orbital planes,having at least 12 satellites in each plane. The siting of the orbital planes is to comply with the Canadian government'sEnhanced Satellite Constellation Project,as well as providing global coverage.[11][12]The constellation is officially namedTelesat Lightspeed.[13]

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 800 kg (1,800 lb) and last 10 years on orbit. The constellation is expected to have a 16-24Tb/scapacity with 8 Tbit/s (1TB/s) available for customers.[14]

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.[15][16][17]

In 2019, Telesat contracted withBlue Originon theirNew Glennrocket andRelativity Spacewith theirTerran 1rocket, for satellite launches to their LEO constellation.[14]

In 2020, Telesat filed plans for expanding the satellite count to its LEO constellation to over 1600 satellites.[12][18]In November 2020, Telesat announced that it will become publicly traded on the American stock indexNASDAQin mid 2021.[19]

In July 2023, LEO 3 satellite was launched.[20]

In Sept 2023, Telesat announced a new contract withSpaceXfor 14 launches with up to 18 satellites on each launch for the Lightspeed constellation, starting in mid-2026.[21]

Services

[edit]

The company is the fourth-largest fixed satellite services provider in the world.[22][23]It owns a fleet of satellites, with others under construction, and operates additional satellites for other entities.

Telesat carries Canada's two majorDBSproviders signals:Bell Satellite TVandShaw Direct,as well as more than 200 ofCanada's television channels.

Telesat's Anik F2 carries aKa-bandspot beampayload for satellite Internet access forWildblueusers in theUnited StatesandXplornetusers in Canada.[24][25]The KA band system uses spot beams to manage bandwidth concerns, linking to multiple satellite ground stations connected to the Internet.
