Researchers Link GPS Disruptions Across Europe to Russian Military Satellites

Scientists have identified a previously overlooked source of GPS interference affecting large areas of Europe: a network of Russian military satellites operating in highly elliptical orbits. The findings suggest that some navigation disruptions traditionally attributed to ground-based electronic warfare may, in certain cases, originate from space.

According to researchers specializing in satellite navigation systems, brief but widespread GPS outages have been recorded across Europe on numerous occasions since 2019. Analysis of signal patterns and timing data indicates that the disturbances are consistent with transmissions originating from Russian early-warning satellites rather than terrestrial jamming systems.

The interference events are generally short-lived, often lasting only a few seconds, but their geographic footprint can extend across multiple countries simultaneously. Experts note that such incidents demonstrate the vulnerability of satellite navigation infrastructure, which supports aviation, maritime transport, telecommunications, financial networks, and critical public services.

The research points to a constellation of Russian military satellites in Molniya orbits as the likely source. Because these satellites spend extended periods over high northern latitudes, they can potentially affect navigation signals across large portions of Europe, Greenland, and parts of North America.

The findings come amid growing concern over GPS interference in Europe. Baltic and Nordic countries have repeatedly reported increased jamming and spoofing activity since Russia’s invasion of Ukraine, with disruptions affecting aircraft, ships, drones, and other navigation-dependent systems. European officials have linked many of these incidents to Russian electronic warfare operations, although Moscow has denied the accusations. (Reuters)

Security analysts warn that interference with global navigation satellite systems is becoming an increasingly important element of modern geopolitical competition. As reliance on GPS and related services continues to grow, governments and industries are accelerating efforts to develop backup navigation technologies and more resilient positioning systems capable of operating during signal disruptions.
