A persistent GPS jammer affecting planes in Estonia is distinct from the Baltic Jammer in Kaliningrad; ongoing efforts aim to characterize and localize it.
On or before April 27, 2024, it was identified that the GPS jammer disrupting aircraft in Estonia is a separate device from the previously documented Baltic Jammer, which has been statistically localized to Kaliningrad through analysis of radio horizon intersections of jammed planes. The Estonian jammer operates almost continuously, with the researcher @auonsson actively collecting sufficient data for localization. This GPS interference disrupts aviation signals, highlighting ongoing electronic warfare challenges in the Baltic region.
Confidence: High
The report clearly describes hostile GPS jamming activity affecting aircraft in Estonian airspace, identifying the jammer as distinct from a known Russian-origin jammer in Kaliningrad, thus qualifying as aggressor activity under cyber and signals intelligence domains.
