What does DSC stand for in maritime communication?

The term DSC in maritime communication stands for Digital Selective Calling. This is a vital feature in modern marine radio systems, specifically within the GMDSS (Global Maritime Distress and Safety System). DSC allows a vessel to send automated distress alerts, including the identification of the vessel and its position, using digital signals.

This system enhances safety by streamlining communication during emergencies, ensuring that distress calls can be sent rapidly and efficiently, with minimal manual input required from the operator. Additionally, DSC is used for routine calls, enabling vessels to communicate directly with one another or with shore stations without the need for voice communication.

This concept distinguishes DSC from other options, which either refer to incorrect terminology or do not capture the specific function and significance of digital selective calling within maritime operations. The use of digital technology in DSC showcases the advancements in maritime safety and communication protocols.
