Globalstar (NASDAQ: GSAT) announced on Aug. 16, 2026, the successful launch and deployment of eight HIBLEO-4 replacement satellites, adding to its low Earth orbit (LEO) satellite constellation.

According to a press release, all eight satellites were dispensed from the launch vehicle and reached their intended orbital planes. Globalstar's Satellite Operations Command Center established communications with each satellite, and all are under the company's command and control.

"The successful launch and deployment of these satellites is an important milestone for Globalstar and our customers around the world," said Dr. Paul E. Jacobs, Globalstar CEO. "With all satellites safely in their intended orbital planes and under our command and control, we are pleased with the mission's progress and are now focused on completing early orbit operations for the satellites to provide additional resiliency across our network."

Initial health assessments indicate the satellites are performing as expected. Engineers are monitoring their status as they progress through early orbit operations.

The satellites will undergo commissioning activities, including system testing and calibration, before being integrated into Globalstar's operational constellation. The company said it will provide additional updates as key milestones are achieved.
