Summary

Between December 8, 2023 and January 3, 2024, a persistent and periodic electronic jammer operating in or around Kaliningrad, or possibly Poland or Denmark, caused widespread loss of positional accuracy for flights in the Baltic region. The finding is based on over 57,000 flight observations analyzed for degraded navigation signal quality, with 281+ jams per hour considered active jamming periods. The jammer’s activity is notably rhythmic and predominantly occurs at night, suggesting operational scheduling. This electronic warfare activity degrades civilian aviation navigation, posing safety risks and indicating sophisticated electronic interference capabilities attributed implicitly to Russian regional electronic warfare. Data sources include independent receiver observations and corroborative heatmaps presented by the researcher @auonsson on social media.

Classification

Confidence: High

The report explicitly identifies an active jammer causing loss of flight positional accuracy, located near Kaliningrad—a known Russian military area—using robust data driven by multiple independent receivers, indicating aggressive electronic warfare targeting civilian navigation signals.
