First set of eight satellites launched on August 15 have passed initial functional tests and payload health checks are underway.

TORONTO, Nov. 10, 2026 /PRNewswire/ — MDA Space Ltd. (TSX: MDA) (NYSE: MDA), a leading provider of advanced technology and services to the rapidly expanding global space industry and prime contractor for the Globalstar 2-R mission confirms all eight of the replenishment satellites launched in August, among the 17 satellites destined for Globalstar, Inc.’s (NASDAQ:GSAT) existing low Earth orbit constellation, have successfully completed initial functional tests. Electric orbit raising has also begun for the first two satellites, and as the orbital planes move into alignment for the remaining six satellites, Globalstar and MDA Space conduct in-orbit testing of the payload and bus functionality.

“From the assembly, integration and testing of Globalstar 2-R satellites to the launch campaign and post-launch activities, we have accomplished multiple mission firsts with fine-tuned skill and agility,” said Mike Greenley, CEO of MDA Space. “As prime contractor for this critical commercial communications constellation, our full focus remains on continued execution and the delivery to our customer.”

Orbit raising for all satellites of the first set will continue with the support of Rocket Lab Corporation (Nasdaq: RKLB), which designed, built and commissioned the satellite platforms, to reach the last testing altitude before they are maneuvered to their final orbit. The final stages of integration were recently completed at MDA Space in Montréal, Quebec, for the remaining batch of nine satellites on order. Both sets, totalling 17 satellites, will replenish Globalstar’s HIBLEO constellation, which supports direct-to-device satellite-enabled services on select mobile phones and IoT applications.
