🔍 Key Concepts

• Inmarsat-C Enhanced Group Call (EGC) services and what they are used for • Difference between SafetyNET, NAVTEX, and other MSI (Maritime Safety Information) services • Role of a Land Earth Station (LES) in routing messages from information providers to ships

💭 Think About

• Which of these choices is specifically tied to Inmarsat satellite broadcasting via LES rather than MF/HF or VHF coastal radio? • Which system is designed to send maritime safety information and navigational warnings to ships over wide ocean regions? • Do any of the options refer to a global or ocean-region coverage service, rather than coastal or voluntary reporting systems?

✅ Before You Answer

• Verify which option is explicitly associated with Inmarsat EGC services and LES operations • Check which system provides broadcasts to defined ocean regions, not limited coastal areas • Eliminate options that are primarily ship reporting systems or medium-range coastal broadcasts rather than global satellite broadcasts
