This is a radio operator certificate designed for certificated navigating officers.

GMDSS is an internationally agreed set of radio technologies that are used to increase safety and make it easier to rescue distressed ships and aircraft. Certain ships are designated as GMDSS ships. The GMDSS safety procedures, equipment types and communication protocols are designed to perform functions such as alerting, search and rescue coordination, locating, Maritime Safety information broadcasts, general communications, and bridge-to-bridge communications.
