Lightspeed 1, ..., 198

Lightspeed is Telesat's Ka-band high-througput broadband communications constellation providing global low-latency internet access, which is initially to be comprised of 198 satellites.

In February 2021 Telesat signed a contract with Thales Alenia Space to build 298 satellites. Telesat will rely on Thales Alenia Space not only to provide the space and mission segments, but also to be responsible for the end-to-end network performance and related specifications of the system.

Lightspeed’s space segment will initially be comprised of 298 satellites, in the 700-750 kg class. The network will deliver multiple terabits per second across the globe for secure, low-latency, high-performing broadband professional services.

Lightspeed is based on an innovative architecture and next generation technologies, providing a very high level of flexibility in capacity allocation. The constellation is built on a unique combination of advanced on-board satellite equipment – sophisticated active antennas that can dynamically refocus beams a thousand times per second, powerful and flexible processors able to address a range of bandwidth, optical laser links between satellites to create a true global mesh coverage of the world – and a mix of on-board and on-ground software ensuring the optimal use of the system resources. The flexibility brought by this system is the key to true competitiveness as it optimizes sellable capacity in relation to the location of demand, which can vary significantly across time and between hot spots such as airports and low-density areas such as remote communities. The optical laser link interconnections between the constellation satellites will provide global, mesh coverage around the world, including above the oceans and poles, with a high level of security for end-to-end services. It will optimize the ground segment with a lower number of gateway sites, more freedom on gateway locations, and the ability to deploy gateways in line with the loading of the system.

The first satellites were expected to be ready for launch in 2023.

In May 2022 it was announced, that the initial constellation was downsized from 298 satellites to 198 and and the contract with Thales Alenia Space was cancelled in favor of a new conract for MDA built smaller satellites.
