Question 40F1
Element 7R (GMDSS-RO)Where NAVTEX cannot be feasibly established, what system can be implemented to provide an automated service in coastal waters to receive MSI?
Explanation
SafetyNET™ is a global, automated satellite-based service within the Global Maritime Distress and Safety System (GMDSS) that broadcasts Maritime Safety Information (MSI). It utilizes the Inmarsat satellite network to provide navigational warnings, meteorological warnings, and search and rescue (SAR) information to ships in all sea areas, including coastal waters (Sea Area A1). Where terrestrial NAVTEX cannot be reliably received or established, SafetyNET™ provides the designated and fully automated alternative for receiving these critical safety messages.
AMVER is incorrect because it is a voluntary ship reporting system used by SAR authorities to track vessel positions for rescue purposes, not for broadcasting MSI to ships. VHF DSC (Digital Selective Calling) is used for alerting and communication, but while it can alert vessels to an MSI broadcast, the full message is typically received via voice or another system, not as a fully automated, print-out service like NAVTEX or SafetyNET™. ARQ SITOR (NBDP) is an older radioteletype system that has largely been superseded by NAVTEX and SafetyNET™ for GMDSS MSI broadcasts.
