GPS Jamming in Contested Waters Demands an All-Source Operational Maritime Picture
GPS Jamming Has Become Routine in Contested Waters Operations in degraded environments are no longer a planning scenario. For anyone responsible for a maritime operational picture, they are already the operating condition in much of the water European navies patrol. GPS jamming touched 124,235 distinct vessels worldwide in Q3 2026, up 11.7% on the previous ...
GPS jamming has become a common occurrence in contested waters, no longer just a planning scenario for navies. In Q3 2026, GPS jamming affected 124,235 vessels worldwide, a 11.7% increase from the previous quarter, according to Windward's Q3 2026 maritime risk report. September was the busiest month, with the Black Sea accounting for 30% of the global jamming.
GPS jamming is an area-level event, affecting every receiver within the zone, including ship AIS positions. In August 2026, Windward found that 61.2% of 642 transits logged through the Strait of Hormuz were false. AIS spoofing is a distinct issue, where a vessel chooses to broadcast false information, making it easy to identify due to discrepancies between reported tracks and physical presence.
Integrating all-source operational intelligence, including AIS, satellite imagery, RF detection, registry data, and behavioral history, is crucial for creating a reliable operational picture, as no single source can survive a degraded environment.
