🔍 Key Concepts

• GMDSS core objectives as defined by the IMO (safety of life at sea, not convenience traffic) • The difference between distress / safety functions and optional or specialized services • What types of communications are explicitly listed in GMDSS requirements (distress alerting, SAR coordination, MSI, etc.)

💭 Think About

• Look at which option describes the full safety communication mission of GMDSS, not just one service or one area • Ask yourself: does this choice cover both ship-to-shore and ship-to-ship safety communications, including before, during, and after a distress? • Identify which answers describe specific tools or services versus the one that lists the functional capabilities GMDSS is built around

✅ Before You Answer

• Verify which option includes distress alerting, SAR coordination, on‑scene, locating signals, MSI, and general/bridge‑to‑bridge functions all together • Check whether any option is limited to a particular service (like Safety‑NET, MSI only) or technology (like direction finding) instead of broad functional requirements • Confirm that the correct option aligns with the IMO description of GMDSS functional requirements, not just a piece of them
