đ 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.)
đ 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, onâscene, locating signals, MSI, and general/bridgeâtoâbridge functions all together
⢠Check whether any option is limited to a particular service (like SafetyâNET, 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
