🔍 Key Concepts

• Digital Selective Calling (DSC) and how it targets specific MMSI numbers instead of all ships • The difference between safety broadcasts (intended for all ships) and directed alerts (intended for one or a few ships) • How satellite Enhanced Group Calls (EGC) and NAVTEX are normally used for wide-area broadcasts

💭 Think About

• For a local storm warning meant only for ships in a small area, would you want a system that alerts every ship in an entire satellite ocean region, or one that can be directed more narrowly? • Which option in the list is specifically designed for selective calling of individual ships or groups, rather than general broadcasts to all ships in range? • Think about which of these systems is primarily an information broadcast service versus a distress/urgency calling system that can target a specific vessel or group.

✅ Before You Answer

• Identify which system uses MMSI (Maritime Mobile Service Identity) numbers to call a specific ship or group • Confirm which systems (EGC, NAVTEX) are used mainly for broadcasting maritime safety information to all ships in an area • Eliminate any option that is primarily a voluntary reporting or tracking system, not a real‑time alerting/calling system
