Hours-long GNSS interference reported in Strait of Hormuz

It is also recommended not to rely entirely on electronic navigation methods or autopilot when transiting through areas prone to GNSS interference and it would be prudent for mariners to consider using traditional non electronic means of position fixing to crosscheck the vessels position when in coastal or congested waters.

Crews of vessels operating anywhere within the UKMTO voluntary reporting area that experience disruptions to electronic navigation systems such as GNSS, AIS, or other positioning, navigation and timing systems are strongly encouraged to note the location and time of the disruption and take photos or video if their ships' electronics or navigation system (if impacted), and report to UKMTO as soon as practicable.
