Russian GPS Interference Identified by University of Texas Researchers
Researchers from the University of Texas have identified a pattern of GPS interference attributed to Russian activities. The interference, which has been occurring since 2019, primarily affects the L1 GPS frequency and has been observed to cause significant drops in signal strength. The interference is not continuous but occurs mainly on weekdays, suggesting a deliberate effort. The University of Texas team, led by Professor Todd Humphreys, used data from 165 reference stations across Europe, Greenland, and Canada to verify these findings. The interference has also been impacting China's Bei Dou satellite navigation system since June 2020.
