What does the acronym "ECC" mean in a DSC message?

The acronym "ECC" in a DSC (Digital Selective Calling) message stands for "Error Check Character." This term refers to a specific character included in digital communications to ensure the integrity of the message being transmitted. The Error Check Character serves as a form of error detection, allowing the recipient to verify whether the data received matches the data that was sent. This is crucial in maritime communication, where clarity and accuracy can be vital for safety.

In this context, the Error Check Character enhances the reliability of the DSC system, which is an essential component of the Global Maritime Distress and Safety System (GMDSS). By incorporating an error-checking mechanism, the system helps to minimize the risks of miscommunication, which can lead to serious consequences in emergency situations at sea. This focus on maintaining reliable and clear communication aligns with the overarching goals of GMDSS.
