2025年11月的太阳超级风暴在美国大陆引发了广泛的电离层扰动，导致GPS定位精度大幅下降1。美国航空航天公司空间物理学家Endawoke Yizengaw领导的研究团队发现，此次风暴造成的GPS偏差在某些地区超过10米（33英尺），这是迄今为止前所未见的规模1。大范围的电离层闪烁现象覆盖从80到120度西经的美国大陆东西向广大地区1。
这次GPS精度失常对依赖高精度定位的应用构成了潜在威胁1。仅1-2米的定位误差就可能对自动驾驶车辆和农业机械造成严重问题1。研究人员通过多个观测仪器的数据分析揭示了此次现象的规模，相关研究成果已发表在《地球物理研究通讯》（Geophysical Research Letters）期刊上1。此前2024年5月的太阳风暴曾对美国农业行业造成约5亿美元的损失1。
A solar superstorm in November 2025 triggered widespread disturbances in Earth's magnetosphere, causing unprecedented GPS malfunctions across the continental United States 1. Researchers led by space physicist Endawoke Yizengaw from the U.S. aerospace company discovered that the geomagnetic event resulted in GPS positioning errors exceeding 10 meters (33 feet) in certain regions 1. The ionospheric scintillation phenomenon extended across a vast east-west corridor spanning from 80 to 120 degrees west longitude, marking the largest-scale disruption of its kind ever recorded 1.
The GPS degradation poses significant risks to precision-dependent applications nationwide 1. Locational inaccuracies of just one to two meters can create serious complications for autonomous vehicles and agricultural machinery, both sectors reliant on precise positioning 1. The research team's findings, published in Geophysical Research Letters, documented the extent of the atmospheric disturbance using data from multiple observation instruments 1. A prior solar event in May 2024 caused approximately $500 million in losses to the U.S. agricultural industry 1.
