Russia's Secret Satellite Network Could Disable GPS Across Europe 2026

Russia has quietly deployed a sophisticated satellite network capable of disrupting GPS signals across Europe, according to a new study. The research, conducted by Professor Todd Humphreys and Zach Clements from the University of Texas at Austin, along with Argyris Kriezis from Stanford University, points to Russia's military early-warning satellite constellation, known as Edinaya Kosmicheskaya Sistema (EKS), as the source of mysterious GPS interference events.

What Is the EKS Satellite Network?

The EKS is a Russian military constellation designed for early warning of missile launches. However, the study suggests it may also be used for electronic warfare. The researchers analyzed public data from GNSS receiving stations and isolated high-power pulses lasting less than 10 seconds that affected receivers simultaneously at various global locations.

By triangulating the signals, they traced the emissions to the EKS satellites operating at an altitude of at least 1,200 kilometers. The interference was detected on at least 75 days between January 2019 and April 2026, specifically in the L1 GPS band.

How the Interference Was Detected

The team collected and analyzed data from multiple ground-based navigation stations. They identified short, powerful bursts that disrupted GPS signals across Europe. These pulses were not random; they were synchronized across different receivers, indicating a deliberate source.

Triangulation techniques allowed the researchers to pinpoint the origin of the signals. The calculated altitude of the emitter matches the orbit of the EKS satellites, leaving little doubt about their involvement.

Implications for Europe's GPS Reliability

GPS is critical for navigation, timing, and communication systems across Europe. Disruptions can affect everything from aviation and shipping to financial transactions and mobile networks. The study raises concerns that Russia may be testing its electronic warfare capabilities or even using the interference as a covert communication channel.

While the interference events were brief, their repeated occurrence over seven years suggests a systematic effort. This could be part of Russia's broader strategy to assert dominance in space and cyber domains.

What the Experts Are Saying

Professor Humphreys is a renowned expert in GNSS security. He and his team have previously warned about the vulnerabilities of GPS to jamming and spoofing. This latest study adds to the growing body of evidence that state actors are developing tools to disrupt global navigation satellite systems.

The researchers emphasize that their findings are preliminary and call for further investigation. However, the pattern of interference is consistent with a military test or operation.
