Question 1 of 27070

When sending a DSC call, the vessel's __________.

🔍 Key Concepts

• Digital Selective Calling (DSC) basics: what information is always included in any DSC call • How MMSI (Maritime Mobile Service Identity) works and what it actually identifies • What extra information is added when a Distress Hot Key is used and the GPS is properly connected

💭 Think About

• Ask yourself: In a normal routine DSC call (not distress), what minimum information must every call contain so the system knows who is calling? • Consider whether an MMSI number contains ocean-region information inside the number itself, or if it mainly identifies the station (ship/shore). • Think about when a vessel’s position is included: is it in every DSC call, or only in specific types of calls or when certain equipment is properly interfaced?

✅ Before You Answer

• Verify what must always be transmitted with any DSC call according to GMDSS practices. • Check whether an MMSI code structure directly encodes an ocean region, or if that’s a misunderstanding of its purpose. • Confirm under what conditions the GPS position is automatically included in a DSC distress alert (e.g., distress button pressed and GPS connected and updated).
