The Global Maritime Distress and Safety System (GMDSS) includes various equipment that support communication, safety, and emergency response for vessels at sea.

Emergency Position Indicating Radio Beacons (EPIRBs)

EPIRBs are designed to send out distress alerts when a vessel is in danger. They transmit the ship’s exact location, helping search and rescue teams respond quickly.

Search and Rescue Transponders (SARTs)

SARTs assist rescuers in locating vessels or lifeboats. Once detected by radar, they appear as a distinct signal on the radar display, making it easier to pinpoint their position.

VHF Radios

VHF radios are commonly used for short-distance communication between ships and coastal stations. They play an important role in distress calls and coordination at sea.

MF/HF
Radios
MF and HF radios provide communication over long distances, especially in areas beyond VHF coverage. They are vital for sending emergency messages across wide ocean areas.

Inmarsat Satellite Communications

This system uses satellites to ensure global communication. It allows vessels to send and receive voice and data messages, including distress alerts, from anywhere at sea.

NAVTEX (Navigational Telex)

NAVTEX is used to broadcast maritime safety information such as weather forecasts, navigation warnings, and urgent updates directly to ships.
