Summary

Headline: Polish Researchers Detect Ship-Based GPS Jammers in Baltic Sea

Short Summary: Polish researchers documented ship-based GPS jamming in the Baltic Sea, impacting navigation and likely originating from vessels operating in international waters.

Description

Polish GNSS researchers detected ship-based GPS jamming in the Baltic Sea. The interference exceeded commercial-grade capabilities, appeared to originate from vessels rather than land, and caused significant navigation errors over several months.

Polish GNSS researchers has determined that the GPS interference observed in the Baltic recently exhibits capabilities beyond commercial grade, and it appears to emanate from ships in transit - not from a fixed land-based source in Kaliningrad, as some analysts have speculated.

If accurate, the apparent discovery of powerful ship-mounted transmitters would help explain the shifting pattern of GPS disruption in the region.

Over a period of six months beginning in June 2024, the sensor picked up 84 hours of GNSS interference, including 29 hours in October alone. Events lasted for up to seven hours at a time, and caused horizontal positioning errors of up to 100 feet.

Multi-constellation jamming (GPS, GLONASS, BeiDou and Galileo) was observed through September 2024; the pattern changed to multi-tone interference from October onwards.

"The interference ... exhibited noticeable fluctuations in power levels, suggesting that the jamming source was in motion... the most plausible explanation is that the jamming originated from a vessel in international waters," the researchers concluded.
