Q

Over what system are Enhanced Group Calls transmitted?

🔍 Key Concepts

• Enhanced Group Call (EGC) as used in the GMDSS (Global Maritime Distress and Safety System) • Difference between satellite-based MSI (Maritime Safety Information) broadcasts and NAVTEX coastal broadcasts • Which system is associated with Inmarsat-C SafetyNET services

💭 Think About

• Is EGC primarily a satellite broadcast service or a terrestrial shore-station broadcast service? • Which listed option is specifically known for transmitting group addressed messages like SafetyNET, FleetNET, and MSI via GMDSS? • Among the options, which one is designed to send safety information to many ships over wide ocean areas rather than just coastal coverage?

✅ Before You Answer

• Identify which option is directly tied to Inmarsat-C GMDSS services • Confirm which system is used for SafetyNET MSI broadcasts (global or ocean-area coverage) rather than local NAVTEX coastal coverage • Eliminate systems that are mainly used for distress alerting, EPIRBs, or short-range NAVTEX rather than EGC group calls
