🔍 Key Concepts

• EGC (Enhanced Group Call) in GMDSS and what it is used for • Difference between SafetyNet and FleetNet services • What kind of information categories are typically bundled in an EGC broadcast

💭 Think About

• Ask yourself: Is EGC primarily about identifying a single ship, or about broadcasting information to groups of ships over a wide area? • Which of these options lists the actual names of Inmarsat EGC broadcast services you’ve seen in GMDSS material? • Would EGC be more connected with distress/safety information, commercial/news information, or internal coding like grounding codes?

✅ Before You Answer

• Verify which pair of names are the recognized Inmarsat EGC services in GMDSS references. • Check whether EGC messages normally carry MMSI (Maritime Mobile Service Identity), or if that’s more associated with DSC and AIS systems. • Confirm that EGC messages also include some form of system/technical information in addition to the named broadcast services.
