Astral Tempest Scrambles GPS Across the U.S., Revealing a New Positioning Vulnerability
During a severe geomagnetic storm on November 11, 2025, GPS positions across much of the continental United States drifted by as much as 10 meters (33 feet) for hours, as an unusually far south auroral oval and a broad band of ionospheric disturbance triggered widespread scintillation—exposing a previously underappreciated vulnerability in systems that rely on ultra-precise positioning and raising questions about prediction.
