US GPS Errors Exceeded 10 Meters in 2025 Solar Superstorm, Scientists Find Coast-to-Coast Glitches
1 articles · Updated · ScienceAlert · Aug 31
Summary
More than 10 meters of GPS error hit parts of the continental US during the November 2025 solar superstorm, with researchers now identifying a coast-to-coast disruption never observed at that scale before.
Endawoke Yizengaw's team linked the failures to strong mid-latitude amplitude scintillation, as storm-driven auroral expansion and sharp electron-density gradients distorted satellite signals crossing the ionosphere.
Observations from aurora cameras and North American GNSS receivers showed irregularities spanning roughly 80 to 120 degrees west longitude, while a broader enhanced-density strip stretched nearly from the West Coast to the East Coast.
Even 1 to 2 meters of positioning error can disrupt autonomous vehicles and precision farming; a separate May 2024 solar storm cost US agriculture an estimated $500 million when navigation failures struck during planting season.
The findings, published in Geophysical Research Letters, underscore how peak solar-cycle storms can expose US industries to space-weather risk and why better forecasting of ionospheric disturbances matters.
With solar activity elevated through 2026, could a sudden mid-latitude space storm permanently blind the GPS networks our autonomous vehicles rely on?
If a 10-meter GPS error strikes during harvest, how will precision agriculture survive the next invisible blow from Earth's volatile magnetosphere?
Solar Superstorm 2025: How a Historic Space Weather Event Exposed Global Infrastructure and Economic Vulnerabilities
Overview
In November 2025, a series of powerful solar eruptions sent multiple coronal mass ejections (CMEs) toward Earth, with the third CME triggering radio blackouts and merging with earlier bursts to create a rare, intense 'cannibal' solar storm. This storm caused brilliant auroras at unusually low latitudes and unleashed energetic particles into the ionosphere, distorting radio and GPS signals worldwide. As GPS accuracy deteriorated, critical sectors like agriculture and aviation suffered, with GPS-guided tractors veering off course and airlines rerouting flights. The storm also threatened power grids by inducing dangerous currents in transmission lines, exposing vulnerabilities in both infrastructure and forecasting systems.
