MDA Space Confirms Eight Globalstar Satellites Functional
Eight replenishment satellites launched in August have completed initial functional tests as part of the Globalstar 2-R mission.
Updated on Nov. 10, 2026 in Space
MDA Space, the prime contractor for the Globalstar 2-R mission, confirmed that all eight replenishment satellites launched in August completed initial functional tests. Electric orbit raising has begun for the first two satellites, with in-orbit testing of payload and bus functionality underway.
Why it matters
The satellites are among 17 destined to replenish Globalstar's existing low Earth orbit constellation, which supports direct-to-device satellite-enabled services on select mobile phones and IoT applications. Successful early testing indicates the constellation renewal is progressing toward service readiness.
Eight satellites completed initial functional tests, with electric orbit raising underway for the first two of 17 total replenishment units. Orbit raising for the first set continues with Rocket Lab support toward the final testing altitude, and the timeline for the remaining satellites has not been disclosed.
The players
MDA Space
MDA Space is a Canadian space technology company headquartered in Montréal that builds satellites and robotic systems for government and commercial customers.
Globalstar
Globalstar is a satellite communications company that operates a low Earth orbit constellation supporting mobile phone and IoT connectivity.
Rocket Lab Corporation
Rocket Lab Corporation is an American space launch and spacecraft company that designs and manufactures satellite platforms.
The details
Rocket Lab Corporation designed, built, and commissioned the satellite platforms, while final integration for nine satellites was completed at MDA Space in Montréal, Quebec. Orbital planes are moving into alignment for the remaining six satellites, which will be maneuvered into final orbit after reaching the last testing altitude.
Timeline
August: Eight replenishment satellites launched.
November 10, 2026: Initial functional tests confirmed for all eight satellites.
Roadmap
The replenishment extends Globalstar's existing HIBLEO low Earth orbit constellation, which already supports direct-to-device satellite services on select mobile phones. The 17 satellites in this program renew that network as the company expands satellite-enabled connectivity.
Successful initial testing moves the replenished Globalstar constellation closer to service readiness for satellite-enabled phones and IoT devices. Users of those services may see improved coverage as the remaining satellites reach operational orbit.
The takeaway
Satellite constellation renewals depend on sequential testing and orbit raising, so early functional confirmation is an important milestone before full service deployment. Readers tracking direct-to-device connectivity can watch for orbit completion announcements from Globalstar and MDA Space.
