GNSS disruption remains concentrated across three maritime corridors
07 Aug 2026
Voluntary reporting recorded 604 GNSS-interference reports year to date — 61 in the previous 30 days — concentrated in the Red Sea, Arabian Gulf and Gulf of Oman.
Situation
Trident's overview recorded 604 voluntary GNSS-interference reports year to date, including 61 in the previous 30 days, alongside 34,236 anomalous AIS positions during the seven-day analytical period. Concentrations persisted in the Red Sea, Arabian Gulf and Gulf of Oman.
What has changed
The geographic footprint remained broadly stable during the reporting period. Interference-report concentrations aligned closely with independently observed anomalous AIS positions.
Operational relevance
Reported interference continues to affect major commercial transit corridors and should remain part of bridge-team navigation-integrity planning.
Trident assessment
The alignment between voluntary interference reports and independently observed anomalous AIS positions increases confidence that both are observing the same underlying disruption. Voluntary reporting is not a complete representation of interference activity.
What to watch
Any expansion of the affected corridors. Because voluntary reports are incomplete, absence of reports in an area should not be read as absence of interference.
