🔍 Key Concepts
• GMDSS locating signals vs distress alerts – what each one is used for
• Equipment that actually helps home-in on a casualty (direction finding / homing)
• Typical locating-signal transmitters: SARTs, survival craft radios / EPIRBs, vs older systems like autoalarm generators
💭 Think About
• Ask yourself: which of these devices sends a signal specifically designed to help rescuers physically home in on the position, not just announce distress?
• Which item in the list is an older, pre‑GMDSS system, and does it transmit a modern GMDSS locating signal?
• For each option, decide: does this equipment send a homing/locating signal, a distress alert, or both?
✅ Before You Answer
• For each device in the options, verify its primary function in GMDSS: distress alert, locating, or both.
• Confirm whether a SART (Search and Rescue Transponder) and a survival craft VHF are identified in GMDSS as locating devices.
• Check if an autoalarm generator is part of the current GMDSS locating-signal suite, or if it belongs to an older radiotelegraphy system no longer used for GMDSS locating.
