Study: November Solar Storm Skewed US GPS by 33 Feet
Researchers found the storm caused widespread scintillation and positioning errors large enough to disrupt precision agriculture and autonomous vehicles, according to Geophysical Research Letters.
- On August 29, 2026, researchers published findings in Geophysical Research Letters detailing how a November 2025 geomagnetic storm shifted GPS readings by more than 33 feet, disrupting autonomous vehicles and precision farming across North America.
- The November 2025 storm, a severe G4 event classified by NOAA, drove the auroral oval toward the equator, creating intense ionospheric density gradients that pushed radio signals off course across the continental United States and Canada.
- Fixed satellite-navigation receivers recorded positioning errors exceeding 10 meters, or 33 feet, during the disturbance. Such deviations render centimeter-level guidance systems used by self-driving cars and automated farm machinery dangerous to operate.
- While the November event occurred post-harvest, researchers noted a similar May 2024 Gannon storm struck during planting, costing American farmers roughly $500 million in potential profits. Widespread navigation outages during peak season could trigger comparable economic losses.
- The event revealed critical vulnerabilities in mid-latitude regions previously considered safe from space-weather interference. Improved space-weather prediction and physics-based modeling are essential, the study concludes, to reduce future disruptions to autonomous systems and precision agriculture.

Solar Storms and Spoofed Signals: Why GPS Blind Spots Threaten Self-Driving Cars
Solar storms and targeted spoofing attacks expose critical GPS weaknesses in autonomous vehicles, with errors exceeding 33 feet. New research reveals motion dynamics amplify vulnerabilities while detection tools lag. Self-driving systems must adapt or risk widespread failure on public roads.
The November 2025 geomagnetic superstorm pushed satellite-positioning errors beyond 10 metres in parts of the continental US, with interference stretching nearly coast to coast. Researchers warn that had it struck during spring planting, it could have caused hundreds of millions of dollars in agricultural losses.
A new reconstruction of the November 2025 G4 storm finds mid-latitude GPS interference across much of the United States, exposing a seasonal risk to precision farming. The post The November 2025 geomagnetic superstorm pushed satellite-positioning errors beyond 10 metres in parts of the continental US, with interference stretching nearly coast to coast. Researchers warn that had it struck during spring planting, it could have caused hundreds of m…
Study: Solar Storm Caused GPS Errors of 33 Feet, Risk to Autonomous Vehicles
A solar storm in November 2024 caused GPS positioning errors exceeding 33 feet across the continental United States, according to a new paper published in Geophysical Research Letters. The report states that global navigation satellite systems experienced significant positioning errors during the storm, which researchers described as large enough to disrupt precision agriculture and autonomous […]
GPS Readings Suddenly Veer Off by 33 Feet, Enough to Crash Self-Driving Cars
According to a report from Futurism published Tuesday, scientists are sounding the alarm after a severe solar storm last November threw GPS readings off by more than 33 feet — a margin large enough to disrupt self-driving cars and precision farming equipment across the continental United States. The storm, the strongest to strike Earth in […]
Scientists confirm solar storms can crash self-driving cars
Scientists have uncovered a surprising weakness in self-driving cars: the Sun. A powerful solar storm sent GPS signals veering more than 33 feet off course, creating errors large enough to disrupt autonomous transportation and potentially put vehicles in danger. But how can a storm millions of miles away interfere with cars on the road — […] Read the original article here: Scientists confirm solar storms can crash self-driving cars
