Russian satellites have been identified as the cause of mysterious, seconds-long bursts of GPS interference across Europe—a rare example of human-made GPS interference coming from space. But uncertainty still hangs over whether such interference is intentional and if it could be more powerfully weaponized as GPS jamming with continental reach in the future. //

Such interference patterns happened mostly on Tuesdays, Wednesdays, and Thursdays during business hours in Europe, Humphreys told the YouTube channel Veritasium. Because such “continental-scale” interference was simultaneously affecting GPS receivers across Europe and beyond, Humphreys and his colleagues calculated that the source had to be at least 1,200 kilometers above the Earth. //

But Russia has been demonstrating a growing number of systems that can potentially neutralize space-based assets belonging to the United States and Europe. In April 2026, the leader of US Space Command warned that Russia had operationalized anti-satellite weapons capable of targeting US government satellites. In May 2026, open source orbital tracking data revealed that at least four Russian military satellites performed orbital maneuvers to match the orbit of a Finnish-American radar surveillance satellite.
