🔍 Key Concepts

• NAVTEX vs EGC (Enhanced Group Call) – which one is for broad area vs more selective broadcasts? • How DSC (Digital Selective Calling) is used for distress/urgency/safety calls on VHF/MF/HF, not satellites • The idea of ‘group’ or ‘selective’ calling so only certain ships or areas receive a message

💭 Think About

• Ask which system is specifically designed to address a selected group of ships or a defined geographic area within a satellite footprint • Consider which option is part of the GMDSS satellite safety net service rather than a purely terrestrial or voluntary reporting system • Think about whether the system is mainly for ship reporting, telex-style text broadcasts, or selective satellite safety messages

✅ Before You Answer

• Verify which option is explicitly associated with Inmarsat SafetyNET services • Check which system allows group or area calls so not every ship in the satellite coverage area is alerted • Confirm that the chosen system is not primarily a voluntary ship-reporting (traffic analysis) program like AMVER
