The Role of Incident Reporting

The advisory encourages the proactive reporting of suspected or confirmed electronic interference incidents, guiding vessels to submit reports through designated forms to the RMI Maritime Administrator and relevant international bodies like the US Coast Guard Navigation Center (NAVCEN) and the NATO Shipping Centre (NSC).

Leveraging Resources for Enhanced Maritime Security

The advisory also highlights valuable resources available to the maritime community, including RMI guidelines, cyber incident reporting forms, and assessments of electronic interferences. These tools are essential for understanding the scope of GNSS and AIS threats and formulating effective countermeasures.

This article delves into the critical aspects of GNSS interference and AIS spoofing as outlined in the Republic of the Marshall Islands' Ship Security Advisory No. 04-24, underscoring the maritime industry's efforts to combat these challenges and ensure safe navigation.
