🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) basic distress alerting via DSC (Digital Selective Calling) • What information is automatically stored in a DSC radio, such as MMSI and default position/time sources • Difference between manual entry by the operator and automatic default data used in a distress alert

💭 Think About

• Think about what a DSC distress alert must contain at a minimum so that a Rescue Coordination Center can begin responding, even if the operator does not type extra text. • Consider what information the DSC unit already knows about the vessel before any distress is sent, and whether that can be transmitted without more operator input. • Ask yourself if other ships or shore stations would be expected to actively "poll" a distressed vessel immediately, or if the first alert must already carry key data.

✅ Before You Answer

• Identify what data is pre‑programmed into a ship’s DSC radio (for example, the vessel’s MMSI number). • Consider whether current GMDSS design allows an operator mistake (forgetting to insert a message) to completely block a distress alert from going out. • Verify whether DSC distress alerts include default position/time information from connected GPS or last‑known position when no additional text is entered.
