In a DSC message, what does the acronym "EOS" stand for?

In a Digital Selective Calling (DSC) message, the acronym "EOS" stands for "End Of Sequence." This term is crucial in the context of the DSC system, which is designed for distress, urgency, and safety communications in maritime environments. The End Of Sequence marker indicates that the transmission of the DSC message has been completed, helping the receiving station understand that no additional data will follow. This is important for ensuring that the message is processed correctly and that no information is overlooked.

Understanding "End Of Sequence" is essential for operators to interpret DSC communications accurately, ensuring safety at sea through effective and clear messaging. Recognizing the conclusion of a message helps prevent confusion during communication and ensures that all relevant parties receive and respond to the information as intended.
