Telesat Lightspeed aiming to break ground early next year

TAMPA, Fla. — Touchdown stations that may hook up with Telesat’s deliberate low Earth orbit (LEO) broadband community will begin being in-built spring 2023, in response to an government for the Canadian satellite tv for pc operator.

Danish tools provider Cobham SATCOM plans to put in the primary of 30 international touchdown stations in Canada, Telesat LEO touchdown station and consumer terminal director Aneesh Dalvi mentioned after asserting their partnership Feb. 1.

Cobham SATCOM constructed the touchdown station for testing the Telesat Section 1 prototype that was launched to LEO in January 2018, and can also be within the technique of changing many of the floor infrastructure for U.S.-based satellite tv for pc operator Globalstar.

Telesat’s touchdown stations can be primarily based on Cobham SATCOM’s TRACKER Gateway sequence, with every comprising a number of Ka-band antennas relying on the topography. 

Beneath the settlement, Cobham SATCOM will make, combine and set up the monitoring antennas that Telesat might want to land indicators from a deliberate constellation of 298 satellites.

The bottom infrastructure can be crucial for offering the 15 terabits per second (Tbps) of world capability that Telesat goals to supply with its full constellation.

These plans hit a stumbling block final yr, nevertheless, with Telesat CEO Dan Goldberg saying Nov. 5 that its satellite tv for pc maker Thales Alenia Area had run into pandemic-related provide chain points which can be delaying manufacturing.

Telesat mentioned it’ll want an extension to fulfill regulatory commitments made with the U.S. Federal Communications Fee consequently, as a result of it now not expects to in a position to deploy half the constellation by Nov. 3, 2023.

Dalvi instructed table4 that the magnitude of the manufacturing delay continues to be unknown as Thales Alenia Area engages with the a whole bunch of suppliers on the undertaking for methods to mitigate the problems.

Telesat, which grew to become a public firm Nov. 19, has additionally not but absolutely secured the ultimate $2 billion of the LEO constellation’s $5 billion value.

From the bottom up

Telesat is shifting full steam forward with the LEO community’s floor infrastructure regardless of the area section delays.

The Canadian operator has introduced vital capability commitments with Canada’s authorities in return for monetary assist, and Dalvi mentioned the corporate expects to get regulatory clearances this yr to construct its first touchdown station within the nation.

Discussions about organising touchdown stations elsewhere are within the works and at “totally different phases for various nations,” he mentioned, including that there can be “some in Europe and in Australia” as a result of Telesat wants websites in northerly and southerly latitudes to assist preliminary launches.

The constellation is being designed with optical inter-satellite hyperlinks (OSL), which reduces its reliance on floor infrastructure to land site visitors. 

“As a result of we have now the [OSL] mesh on all of the satellites, we will present service wherever on this planet with just one touchdown station to start with,” Dalvi mentioned.

Nonetheless, he mentioned “every OSL hop” provides about 5-10 milliseconds of latency, relying on the geography. 

That makes it difficult to remain throughout the firm’s 50-millisecond latency goal “if it’s important to backhaul the site visitors over the OSL mesh midway all over the world or one thing like that,” he mentioned.

Dalvi estimates it’ll take Telesat and Cobham SATCOM about three to 4 months to arrange a touchdown station after clearing all regulatory hurdles.

Their settlement consists of the choice to deploy greater than 30 touchdown stations if demand requires it.

He mentioned Telesat Lightspeed has additionally chosen a consumer terminal provider, however declined to debate particulars.
