Expert Calls for Urgent Modernization of U.S. GPS Satellite System

GPS Innovation Alliance executive director Lisa Dyer warns that the U.S. must urgently modernize its aging and vulnerable GPS satellite constellation. She urges the Department of Defense to launch three next-generation GPS satellites currently in storage and adopt a “launch upon availability” strategy. Dyer stresses the need for immediate action, advocating for launches using available rockets like SpaceX’s Falcon 9 or ULA’s Vulcan. Additionally, she calls on Congress to fund two GPS IIIF satellites per year and upgrade ground stations to support new civil signals. The proposal highlights growing concerns over GPS reliability and national security in an evolving threat landscape.
