Summary

On April 9, 2024, starting at 15:20 UTC, the Russian Baltic GPS jammer began operations emitting high output signals that disrupted navigation systems on approximately 40 unique aircraft. This represented the highest output since a similar event on March 27, 2024. After roughly 30 minutes, the jammer's intensity was reduced, narrowing its interference impact to planes operating near Gdansk, Poland. The jammer operation ended within an hour, marking this as the shortest full-effect Baltic jammer run recorded to date, lasting about 30 minutes at full power. The jammer had previously operated mainly at low power affecting only the Gdansk area. This event was monitored and reported by aviation tracking and monitoring sources.

Classification

Confidence: High

The event clearly describes hostile Russian GPS jamming activity targeting Baltic aviation navigation near Gdansk, Poland. The operator and purpose of the jammer are explicitly identified in the thread.
