What does GMDSS stand for?

The correct answer is "Global Maritime Distress and Safety System." This system is essential for ensuring maritime safety and communication, particularly in distress situations. GMDSS coordinates various communication methods, including satellite and terrestrial radio systems, to facilitate the rapid transmission of distress signals and information related to maritime safety, making it a critical component for maritime operations.

It incorporates a wide range of technologies and processes designed to enhance safety at sea. For instance, the GMDSS allows vessels to send alerts through different frequencies and platforms, ensuring that they can effectively communicate with rescue services and other ships in the vicinity during emergencies.

The other options are variations that either omit key components or mischaracterize the system, lacking the specificity and recognizability of the full title that is commonly used within the maritime industry.
