Russian GPS jamming in Kaliningrad stopped and reduced near St Petersburg; NATO increases Baltic Sea maritime surveillance amid suspicions of GPS spoofing misdirecting Ukrainian drones and false AIS ship data manipulation affecting sanctioned tanker monitoring.

Summary

On June 9, 2024, Russian electronic warfare operations involving GPS jamming and spoofing around Kaliningrad and St Petersburg were substantially reduced. The Kaliningrad jammer, which had been active nightly for months, was turned off, and the St Petersburg jammer, previously operating permanently with some exceptions, was drastically toned down. This change markedly improved GPS navigation signals for airliners in the Baltic region, evident from ADS-B message data showing reduced low navigation quality indications over the prior 2.5 days. The disruption had affected commercial air traffic navigation accuracy, suggesting a significant electronic warfare campaign by Russia targeting Baltic airspace and navigation systems. The cessation on June 9 indicates a notable shift in Russian EW tactics or operational posture in the area.

Classification

Confidence: High

Concrete technical evidence of Russian electronic warfare via GPS jamming and spoofing aimed at military and civilian aviation navigation, alongside maritime data manipulation involving a sanctioned tanker and false AIS tracking demonstrating hostile hybrid warfare activity in the Baltic and adjacent regions.

  "description": "As of early morning June 9th, 2024, the Russian GPS jamming activities in Kaliningrad have ceased and jamming in St Petersburg has been drastically reduced after running nightly and permanently respectively for months. The jamming targeted ADS-B messages of airliners in the Baltic region, impacting flight navigation quality. One Russian GPS spoofer near St Petersburg appears to have an aim function possibly used to misdirect Ukrainian attack drones into NATO territory, with reports of such drones straying into Finland, Estonia, and Latvia. NATO and Baltic nations have increased maritime surveillance in the Baltic Sea, requesting mariners report suspicious activities via VHF channel 16 to protect navigation and undersea infrastructure. A sanctioned aged and deficient tanker \"GRIF\" flagged falsely under Madagascar is transiting the Baltic Sea toward Russia without hindrance. False AIS data spoofing simulating ship movements near the Hormuz Strait has been detected, misleading observers about shipping traffic. Recently, a lull in sanctioned tankers arriving in the Baltic Sea has been observed, possibly due to weather and ice buildup, compounding Russia's capacity issues with Baltic oil terminal ice navigation. Notably, submarine cable damage around New Year 2026 targeted Estonia's internet backbone routes, which if fully successful, would have severely disrupted Estonia's connectivity. Baltic States and UK have made diplomatic moves to restrict sanctioned shipping in the Baltic Sea.",
