Telesat, Calian to work on data for Telesat Lightspeed

Executive Summary

• Telesat and Calian Group Ltd. have entered into an agreement to design, develop, integrate and deploy the operational data platform for the Telesat Lightspeed LEO satellite network.
• The platform will provide a secure, real‑time data backbone across satellites, landing stations and user terminals, enabling bidirectional asynchronous data flows, high availability, situational awareness and automated mission response.
• This contract expands Calian’s existing role (EMS delivery in 2024) and leverages Calian’s proprietary Centralized Management Platform (CMP) as the architectural foundation.

Key Details

• Parties: Telesat LEO ULC (wholly owned subsidiary of Telesat Corp.) and Calian Group Ltd.
• Scope of Work: Design, development, integration and deployment of the Telesat Lightspeed operational data platform; implementation of secure, real‑time data backbone across the LEO constellation, ground infrastructure and user terminals.
• Technology Basis: Calian will use its proprietary Centralized Management Platform (CMP) to ensure high performance, robust security and extensibility across public and private cloud environments.
• Functional Capabilities: Supports bidirectional asynchronous data flows, high‑availability across multiple domains, real‑time situational awareness, automated mission response, and secure data exchange between network components and downstream operational/business platforms.
• Strategic Importance: Provides the digital infrastructure needed for mission‑critical connectivity in defence, enterprise, telecom and mobility markets; enhances Canada’s strategic national capability for secure global communications.
• Historical Context: Calian previously delivered the Element Management System (EMS) for Telesat Lightspeed in 2024, managing health of user terminals, landing station antennas and onboard satellite systems. This new agreement expands that relationship.
