GPS jamming has come to space. Researchers have identified a Russian satellite as the source of 10-second radio bursts that have been disrupting GNSS signals.

Occasional bursts of energy from a Russian missile-detection satellite have been briefly disrupting satellite navigation across large parts of Europe, a pattern that may indicate a “qualitative escalation in GNSS [global navigation satellite system] interference.” 

At least 75 times between 2019 and 2026, University of Texas researchers observed 10-second bursts of high-powered radio signals at 1558.5 MHz: the frequency used by GPS and European navigation satellites to transmit signals to Earth. The bursts disrupted GPS antennas from Romania to Greenland, the researchers write in a paper published this month in the journal Navigation.
