Solar Superstorm Disrupts GPS, Skewing Self-Driving Cars

A November 2025 geomagnetic storm disrupted GPS signals for hours over much of the U.S. and Canada, causing positioning errors of over 30 feet (about 10 meters) that could affect precision farming and autonomous vehicles; researchers mapped ionospheric disturbances using aurora observations and GPS networks, underscoring the need for better space-weather forecasting to mitigate impacts on critical tech.
