Multiple instances of significant GPS interference continue to be reported by vessels and aircraft operating in the Eastern Mediterranean Sea.
These reports have been concentrated near Port Said, Egypt, the Suez Canal, and in the vicinity of the Republic of Cyprus.
Additional instances of similar interference were reported in October 2018 near Jeddah Port, Saudi Arabia.
This interference is resulting in lost or otherwise altered GPS signals affecting bridge navigation, GPS-based timing and communications equipment. Navigators have been advised to exercise caution when transiting these areas.
