Summary

On April 15, 2025, Finland’s National Land Survey (Maanmittauslaitos) started a two-year, EU-funded project to develop and test methods to counter satellite positioning (GPS) interference attributed to Russia. The project targets satellite navigation disruptions causing problems for aviation, maritime traffic, and aerial imaging. Testing is being conducted in North Karelia, Finland, aiming to better identify and mitigate satellite navigation jamming and its associated damages.

Classification

Confidence: High

Classified as aggressor event because the interference is attributed to Russia causing GPS disruptions. Classified as defense preparation because Finland’s National Land Survey is developing and testing countermeasures starting in April 2025 as an EU-funded project.
