Telesat and MDA Space Has Concluded A Key Phase In The Telesat Lightspeed Low Earth Orbit Constellation Program With The Successful Completion Of The Spacecraft Preliminary Design Review

Telesat (TSX:TSAT), one of the world's largest and most innovative satellite operators, and MDA Space (TSX:MDA), a trusted mission partner to the rapidly expanding global space industry, today announced that they have concluded a key phase in the Telesat Lightspeed low Earth orbit (LEO) constellation program with the successful completion of the spacecraft Preliminary Design Review (PDR).

The PDR is a critical checkpoint in the program. Its successful completion demonstrates maturity in the design that meets the program's functional and performance requirements. As part of the process, the PDRs for multiple key subsystems have also been successfully completed.

The Telesat Lightspeed LEO satellite constellation is an innovative, advanced global network that will bring enterprise-class connectivity to customers worldwide. Telesat selected MDA Space as the prime satellite contractor for the constellation in 2023, awarding an initial order for 198 satellites powered by MDA AURORATM technology, the company's new digital satellite product line.

With PDRs completed, Telesat and MDA Space are now transitioning to the program's detailed engineering and manufacturing phase, including the Critical Design Review.
