The situation has increased the threat to vessels from collateral damage in the Arabian Gulf/Persian Gulf and Gulf of Oman. Several examples of GPS-Spoofing towards vessels are already observed in the Arabian Gulf / Persian Gulf and Red Sea.

Due to the military actions across the waters of the Middle East peninsula, there is a high degree of uncertainty of the situation in the Persian Gulf, Strait of Hormuz and Gulf of Oman.  

There is a high degree of GNSS interference towards vessels in the whole area. 

NMA would like to highlight the importance of conducting a comprehensive security assessment before the vessel enters the area with MARSEC/ISPS-level 3.
