• JRC GMDSS System

The Global Maritime Distress and Safety System (GMDSS) is an international system that uses terrestrial and satellite technology and ship-board radio systems to ensure rapid, automated alerting of shore-based communication and rescue authorities, in addition to ships in the immediate vicinity, in the event of a marine distress.

Under the GMDSS, all cargo ships of 300 gross registered tonnes and upwards and all passenger ships engaged on international voyages must be equipped with radio equipment that conforms to international standards as set out in the system.The basic concept is that search and rescue authorities ashore, as well as shipping in the immediate vicinity of the ship in distress, will be rapidly alerted through satellite and terrestrial communication techniques so that they can assist

in a co-ordinated search and rescue operation with the minimum of delay.

The GMDSS also requires ships to receive broadcasts of maritime safety information (MSI) which could prevent a distress from happening, and requires ships to carry satellite emergency position indicating beacons (EPIRBs), which float free from a sinking ship and alert rescue authorities with the ship's identity and location.
