Solar storm impact on US GPS accuracy
Overview
A severe G4-level solar storm occurring in November 2025 caused significant disruptions to Global Positioning System (GPS) accuracy across the continental United States. Triggered by coronal mass ejections interacting with Earth’s magnetic field, the geomagnetic disturbances altered the ionosphere and created intense density gradients in the upper atmosphere.
These fluctuations resulted in horizontal positioning errors exceeding 10 meters (33 feet). The inaccuracies impacted various critical sectors, including aviation, maritime navigation, drone technology, drilling operations, and precision agriculture. Additionally, the solar activity forced NASA to delay a Mars-bound spacecraft launch.
