GNSS jamming reported in Strait of Hormuz
Multiple reports documented GNSS jamming incidents in the Strait of Hormuz, exposing maritime navigation and geospatial infrastructure vulnerabilities in a high‑risk region reported. The event raises fresh concern for geospatial threat intelligence and resilient positioning strategies used by defense and maritime operators.
Maritime analytics firm [Windward reported]windward.ai that more than 1,100 vessels experienced GPS and AIS interference within a single 24‑hour period (reported Mar 1, 2026), with affected tracks repeatedly relocating ships onto airports, a nuclear power plant, and inland Iranian and Gulf locations. windward.ai The Joint Maritime Information Centre (JMIC) [advised]gcaptain.com on March 10 that the Strait of Hormuz operational area remained at a “critical operational risk level” after more than 600 GNSS disruption events were recorded in the previous 24 hours, citing positional offsets, AIS anomalies, and intermittent signal degradation. gcaptain.com Vessel‑tracking platform [MarineTraffic identified]gcaptain.com a new interference signature off Ras Al Khaimah beginning at 15:00 UTC that produced long linear AIS traces inconsistent with actual ship headings, prompting analysts to label the pattern “straight‑line” spoofing rather than routine clustering. gcaptain.com Aggregators and regional monitors placed the cumulative disruption scale between Windward’s 1,100+ estimate and GIS Resources’ assessment of roughly 1,650 impacted ships as of March 11, 2026, with Inside GNSS and industry insurers reporting slowed transits, “dark” operations, and the withdrawal of war‑risk coverage for vessels in the chokepoint. windward.ai
