Question 40F6
Element 7R (GMDSS-RO)Maritime Safety Information is promulgated via satellite through which system?
Explanation
SafetyNET™ is a global, automated, direct-printing satellite service used to broadcast Maritime Safety Information (MSI) as an integral part of the Global Maritime Distress and Safety System (GMDSS). It utilizes the Inmarsat satellite network to deliver crucial information like navigation and meteorological warnings, and search and rescue alerts directly to ships at sea.
NAVTEX, while also broadcasting MSI, is a terrestrial system operating on medium frequency (MF) radio, not via satellite. AMVER (Automated Mutual-assistance Vessel Rescue system) is a voluntary ship reporting system used by the US Coast Guard for search and rescue coordination, not for broadcasting general MSI. Inmarsat-M SES refers to a specific type of Inmarsat satellite terminal (Ship Earth Station) and its service, but SafetyNET™ is the *system* designed for the broadcast of MSI via the Inmarsat satellite network, typically to Inmarsat-C terminals.
