On August 23, 2024, Finnish flights to and from Joensuu near the Russian border were canceled due to sustained GPS jamming at a high (~7%) level.

Summary

In August 2024, GPS jamming in Finnish airspace, particularly near Joensuu close to the Russia-Finland border, stabilized at a high level of around 7%. The last reported incidents were on August 23, when flights to and from Joensuu were canceled or turned back due to interference. This level of GPS disruption is significantly higher than that caused by the Kaliningrad jammer, which affects roughly 1% of daily flights. The sustained jamming indicates ongoing technical electronic warfare efforts targeting Finnish civilian aviation navigation in a sensitive border region, likely linked to Russian operations.

Classification

Confidence: High

The event clearly describes hostile GPS jamming targeting Finnish airspace near a sensitive border, disrupting flights. The actor is implied to be hostile (consistent with Russian hybrid warfare techniques), and no defense/preparation measures are described.
