TSAT Telesat Corporation

Telesat (NASDAQ and TSX: TSAT), one of the world’s largest and most innovative satellite operators, today announced that it has selected Calian Group Ltd. (TSX:CGY), an Ottawa-based company with deep experience in delivering advanced technology solutions for the space, defence, and terrestrial sectors, to design, develop, deliver and deploy the Element Management System (EMS) within the Telesat Lightspeed Low Earth Orbit (LEO) satellite network as well as to provide lifecycle maintenance and support for the system.

The EMS will be instrumental in connecting and maintaining operations for various components within the Telesat Lightspeed network, identifying and addressing issues to ensure optimal performance. With the EMS, Telesat will be able to manage the configuration and capabilities of Telesat Lightspeed Landing Stations, User Terminals, and the satellite onboard processors as needed. In addition, Telesat will leverage the EMS to collect and share Telesat Lightspeed system data with the company’s Operations Support Systems and Network Operations Centers to gain full visibility into the state of the entire constellation.

“We are excited to support the Telesat Lightspeed LEO network with essential software and services for this cutting-edge satellite constellation,” said Valérie Travain-Milone, President, Advanced Technologies, Calian. “By enabling high-speed connectivity in remote and underserved areas, Telesat Lightspeed will empower industries and communities across Canada and beyond. We’re proud to contribute to this transformative project, ensuring reliable, affordable internet access on land, at sea and in the air.”

The Telesat Lightspeed constellation is a network of advanced LEO satellites and integrated terrestrial infrastructure that will offer high-speed, low-latency broadband connectivity to remote locations across Canada and worldwide. The Telesat Lightspeed network will support multi-Gbps data rates for government, aeronautical, maritime and enterprise customers, including industries such as oil and gas that operate in locations without access to fibre. Telesat Lightspeed will also help to bridge the digital divide, by expanding the reach of telecom networks in unserved and underserved areas.

“The EMS is a critical component of the orchestration of system segments in this advanced, enterprise-class network,” said Aneesh Dalvi, Vice President for Telesat Lightspeed Systems Development. “We conducted a thorough search to find an innovative partner that could meet our requirements and Calian demonstrated the technological knowledge and expertise to deliver this capability; selecting them is a significant milestone as we push toward the launch of the Telesat Lightspeed network.”

Calian’s EMS technology will play a crucial role in the network operations for Telesat Lightspeed, the largest space program in Canada’s history. In addition to helping to bridge the digital divide, the Telesat Lightspeed network is creating and sustaining thousands of high-quality Canadian jobs and puts Canada at the forefront of the burgeoning New Space Economy.
