Globalstar Announces Upcoming HIBLEO-4 Satellite Replenishment Launch with SpaceX

Globalstar announced that Globalstar’s HIBLEO-4 replenishment satellites will launch on a SpaceX Falcon 9 rocket on Sunday, May 17 during a 14-minute window that opens at 8:50 a.m. ET, from Cape Canaveral Space Force Station in Florida.

The satellites are designed to help replenish Globalstar’s existing low Earth orbit constellation, supporting continued network resilience and service reliability across the company’s satellite communications offerings.

The launch is part of Globalstar’s ongoing investment in its current-generation satellite infrastructure as the company continues advancing its broader network roadmap.

“This launch represents another important step in sustaining and strengthening the infrastructure our customers rely on every day,” said Dr. Paul E. Jacobs, Chief Executive Officer, Globalstar. “As we continue executing our long-term strategy, replenishing our existing constellation remains a critical part of delivering resilient satellite services around the world.”

Additional launch updates will be shared as they become available. A live mission webcast will be available on spacex.com/launches beginning approximately 15 minutes before liftoff.
