What is the Global Maritime Distress and Safety System (GMDSS) known for?

The Global Maritime Distress and Safety System (GMDSS) is recognized for its use of modern technology, including satellites, to effectively transmit distress signals and enhance safety at sea. This system serves as a vital communication link for vessels, enabling them to send distress alerts and messages to search and rescue authorities in a reliable manner. By integrating satellite communication, along with digital selective calling, VHF radiotelephony, and other advanced technologies, GMDSS provides a robust and efficient means of ensuring that help can be summoned quickly in emergencies, regardless of the vessel’s location.

The other options do not accurately represent the functions of GMDSS. For example, the idea that the system uses only terrestrial systems is misleading since it incorporates both terrestrial and satellite-based systems. Furthermore, framing GMDSS as antiquated and mainly manual overlooks the cutting-edge technology it employs to ensure prompt and effective communication. Lastly, the suggestion that it only functions in national waters fails to account for the global reach of GMDSS, which operates effectively in international waters as well as within national maritime jurisdictions.
