Die Forscher identifizierten 75 Tage GPS-Bremsen von russischen Satelliten, mit Ausbrüchen, die von Norwegen bis Kanada nachweisbar waren.

75 days of GPS interference across Europe, each burst under 10 seconds, yet detectable simultaneously from Norway to Spain to Poland and even across the Atlantic in Greenland and Canada. That's the pattern Todd Humphreys and Zach Clements at The University of Texas at Austin, along with Argyris Krizise at Stanford University, pulled from public ground-station data spanning January 2019 through April 2026.

75 Days of 10-Second GPS Bursts

The team sifted through data from ground-based GNSS receivers and found high-powered interference on the GPS L1 frequency band centered at 1575.42 MHz. That's the main band used by the US GPS constellation and other GNSS systems. The bursts hit multiple stations at the same time, meaning the jamming wasn't local—it came from space. Russian satellites are the only plausible culprit, given the geographic and orbital patterns.

The UT Austin–Stanford Team Tracked the Source

Humphreys, Clements, and Krizise didn't invent new hardware; they used publicly available data from existing monitoring networks. The preprint details how the interference events cluster around specific Russian satellite passes over Europe. The precision of the timing and the wide simultaneous coverage strongly suggest the jamming originates from orbiting transmitters, not ground-based equipment.

What This Means for Continental-Scale Jamming

The uncertainty lies in intent. Are these tests of a weaponized capability, or accidental bleed-through from satellite operations? Either way, the data proves Russian satellites can inject enough power into the GPS L1 band to disrupt reception across an entire continent. A few seconds of blackout can mess with aviation, maritime navigation, and financial network timing. If the bursts were longer or coordinated, the impact scales from annoyance to systemic failure.

The paper leaves the weaponization question open. But the engineering community now has a clear dataset and a named mechanism. Next step: figure out how to shield against a space-based jammer that can reach from Norway to Canada in a single pulse.
