Russian EW systems likely affect GPS operations in Poland and Baltic region — ISW
The Russian electronic warfare system (EW) jams GPS signals in Poland and the Baltic region. Recently, large-scale disruptions were recorded there
Analysts at the Institute for the Study of War write about this.
It is noted that the Polish radio station Radio Zet cited data from the GPSJAM GPS interference tracking site from January 16, which shows an unprecedentedly high level of GPS jamming in northern and eastern Poland, including Warsaw and in the south to the city of Lodz.
Instead, GPSJAM data also shows similarly high levels of GPS jamming across the southern Baltic Sea and northwestern and central Poland between December 25-27, 2023, and on January 10, 2024.
At the same time, Polish media speculate that the December 2023 outages may have been caused either by unspecified NATO military exercises in the Baltic region or could be linked to recent Russian EW tests in the Kaliningrad region.
In addition, Sweden's Military Intelligence and Security Service opened a case into the disturbances on January 12 in light of Russian Baltic Fleet EW exercises. Swedish Lieutenant Colonel Joakim Paasikivi stated on January 6 that he believes that recent GPS interference levels are a result of "Russian influence activities or so-called hybrid warfare."
He also added that Russia has previously interfered with GPS signals in northern Europe to protect Russian activities in Murmansk region or disrupt NATO exercises.
- On January 14, Ukrainian Air Force spokesman Yuriy Ihnat said that local authorities could buy electronic warfare equipment to protect communities from Russian missile strikes.
