Question 1 of 29218

What equipment is programmed to initiate transmission of distress alerts and calls to individual stations?

🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) functions for distress alerting vs safety information reception • What DSC (Digital Selective Calling) is designed to do on VHF/MF/HF radios • The difference between equipment that only receives broadcasts and equipment that can originate a distress call to a specific station

💭 Think About

• Which of these devices is specifically linked to the radio set to send a formatted distress alert or an individual call, rather than just providing position or receiving messages? • Think about which unit you would actually operate or program to send a distress alert to a particular coast station or ship under GMDSS. • For each option, ask: does this device mainly provide navigation data, safety info broadcasts, or does it control who the radio calls and how the call is set up?

✅ Before You Answer

• Verify which equipment in GMDSS is used for Digital Selective Calling (DSC) functions, including distress, urgency, safety and routine calls. • Check which device is primarily a receiver of maritime safety information (MSI) and does not initiate calls. • Confirm which of the listed devices is capable of sending a distress alert to a specific MMSI (Maritime Mobile Service Identity) number or all ships.
