DSC is primarily used to?

DSC, or Digital Selective Calling, is a crucial communication system used primarily for transmitting and receiving Distress and Urgency alerts in maritime operations. This digital technology enhances the safety of vessels at sea, allowing ship operators to send a distress signal quickly and automatically to all ships in the area, the coast guard, and other relevant authorities.

When a vessel experiences an emergency, the DSC system enables rapid activation of distress calls, which include detailed information such as the vessel's identity and current location, significantly speeding up the rescue response. This capability is vital in life-threatening situations, making immediate alerts to nearby vessels and rescue operations critical.

In contrast, options discussing receiving weather warnings, routine communication with ship owners, or reporting positions via satellite do not capture the primary function or significance of DSC, which is specifically designed for emergency communications.
