Solar Storm Triggers 33-Foot GPS Errors, Threatening Self-Driving Tech

A new study finds a November solar storm caused significant GNSS errors—over 33 feet—across the continental US due to auroral activity and upper-atmosphere density changes, degrading GPS signals and potentially disrupting precision farming and autonomous transport; a May 2024 storm previously cost farmers about $500 million, underscoring the need for better space-weather forecasting to mitigate disruptions to RF systems.
