The primary purpose of the GMDSS is to:

• A. Automate and improve emergency communications for the world's shipping industry
• B. Provide weather forecasts
• C. Track ships for port arrivals
• D. Provide onboard entertainment

Answer: (A)

Global Maritime Distress and Safety System (GMDSS) is designed to ensure that distress and safety communications are automated, standardized, and available worldwide. Its primary purpose is to automate and improve emergency communications for ships operating anywhere, so distress alerts and safety information are transmitted quickly to rescue authorities and coordinating centers, no matter where the vessel is. It uses a mix of satellite and terrestrial systems (such as satellite networks, digital selective calling on VHF, MF, and HF channels, NAVTEX for safety broadcasts, and coordinated distress signaling) to speed up response and coordination in emergencies, a framework that supports rapid rescue under SOLAS rules. Weather forecasts and port-traffic tracking serve important maritime needs but are not the main goal of GMDSS, and onboard entertainment is unrelated to safety communications.
