TSAT Telesat Corporation

Telesat (NASDAQ and TSX: TSAT), one of the world’s largest and most innovative satellite operators, and Intellian, a leading provider of feature-rich, future-proof satellite communications solutions, today announced a contract award for Intellian to design, supply, install, and integrate 127 Gateway Antenna Systems at Landing Stations for the Telesat Lightspeed Low Earth Orbit (LEO) constellation.

Intellian’s 4-meter Gateway Antenna System has been meticulously engineered to optimize tracking precision and high gain performance for LEO satellites and durability in all weather conditions. Built to withstand the harshest environments without the need for radomes, the Gateway Antenna System not only enhances RF efficiency, it also reduces long-term maintenance and energy costs.

The Telesat Lightspeed Landing Stations play a crucial role in the delivery of Telesat’s enterprise-class services. Each Landing Station will be equipped with multiple Intellian Gateway Antennas, as well as baseband, network, and control systems. These stations will route customer data to Points-of-Presence for telecom networks, internet, and cloud services, and will also facilitate private interconnections for customer networks.

Eric Sung, CEO at Intellian Technologies Inc said: "Our collaboration with Telesat has been exceptional, and the resulting Gateway Antenna Systems are a fascinating addition to our portfolio. Seeing how our heritage and experience in delivering innovative design solutions transitioned over to gateway antennas has been very rewarding. This evolution with Telesat solidifies the crucial role we play within the satellite communications ecosystem even more.”

“Intellian has been a valued partner in flight operations and testing programs with Telesat’s LEO demonstration satellites; their proven performance and innovation makes Intellian an ideal partner for our advanced LEO satellite program,” said Aneesh Dalvi, Vice President for Telesat Lightspeed Systems Development. “Intellian’s engineering excellence and state-of-the-art manufacturing facilities were key drivers in this contract award. We have the right partner to ensure that our global terrestrial infrastructure is deployed and integrated with our space assets to deliver services globally in 2027.”
