What is the fundamental concept of the GMDSS?

Correct Answer: Option A — It is intended to automate and improve emergency communications in the maritime industry.

GMDSS replaces manual Morse code watchkeeping with automated systems. By utilizing satellite and terrestrial digital technology, it ensures rapid, reliable distress alerting and coordination. This shift from human-dependent monitoring to automated digital selective calling (DSC) significantly improves the probability of successful search and rescue operations globally.
