Which of these can be used to receive MSI?

🔍 Key Concepts

• Maritime Safety Information (MSI) is routine safety info like navigational warnings, weather, and SAR information • Different GMDSS equipment types have different primary purposes: alerting/distress vs. two-way communication vs. safety information broadcasts • Identify which devices are mainly for transmitting a distress alert and which are for receiving scheduled broadcasts

💭 Think About

• First, recall what MSI includes and how it is normally distributed to ships under GMDSS. Which services or systems carry these broadcasts? • For each option, ask: Is this primarily a distress-alerting device, a homing/locating device, or a communication/broadcast reception system? • Think about which equipment is used to receive NAVAREA warnings, meteorological forecasts, and navigational warnings automatically, without operator intervention.

✅ Before You Answer

• Check which options are used mainly to send a distress alert rather than to receive routine safety information • Verify which equipment is designed for homing/locating a survival craft, not for message reception • Confirm which of the choices are explicitly listed in GMDSS as MSI reception systems (worldwide and coastal) rather than purely distress-alert systems
