Tests Suggest Russian Satellites Can Jam GPS on a Continental Scale
Researchers say 75 interference events since 2019 point to Russian early-warning satellites, with GPS L1 drops of up to 10 dB.
- Researchers led by Professor Todd Humphreys of the University of Texas traced persistent GPS interference events across Europe, Greenland, and Canada to Russian early-warning satellites in the Edinaya Kosmicheskaya Sistema constellation.
- These interference events occur in sharp, intense bursts lasting less than 10 seconds, primarily during business hours on Tuesdays through Thursdays, centered at 1577.5 MHz slightly offset from standard GPS frequencies.
- Using data from 165 reference stations, Humphreys and Zach Clements calculated a "quasi-hyperboloid surface" in space, pinpointing the Russian satellite Kosmos 2546 with five meters of accuracy.
- Humphreys stated this represents a "massive escalation" in electronic warfare, noting the same Russian constellation has impacted signals from China's Bei Dou satellite navigation system since June 2020.
- While Russia may not destroy GPS satellites, the ability to prevent signal reception creates tactical advantages; consequently, the United Kingdom, France, South Korea, and Saudi Arabia are building terrestrial systems to protect economic security.
