Vessels that are involved in jamming or spoofing critical location signals have increased their average distance “jump” to 6,300km from 600km in the first quarter of 2025.
This distance “completely disrupts trade and safety measures at sea”, making it nearly impossible to track vessels within any realistic or relevant geographical vicinity, according to data analyst firm Windward.
The maritime intelligence firm made the discovery while investigating how geopolitical disruptions and sanction regimes had altered vessels’ operating patterns.
