The Global Maritime Distress and Safety System is based upon a combination of satellite and terrestrial radio services, changing international distress communications from being primarily ship-to-ship based to ship-to-shore based. It has spelled the end of Morse code communications for all but a few users.

Global Maritime Distress and Safety System. Minimum safety standards agreed to by the International Maritime Organization (IMO).
Global Maritime Distress and Safety System. An international system that uses terrestrial and satellite technology to provide automated alerting of shore-based rescue authorities, in addition to ships in the vicinity, in the event of a maritime distress situation.
Global Maritime Distress and Safety System Regulations on radio equipment for vessels over 300 GT requiring Digitally Selective Communication. Smaller vessels should also have certain equipment in order to communicate with new distress frequencies in order to be able to assist other vessels.
Global Maritime Distress and Safety System, a global communication system enabling vessels in distress to transmit distress signals to nearby coast stations and vessels.
The Global Maritime Distress and Safety System: the Inmarsat-A/B and C systems are the only Inmarsat networks included in the GMDSS by the IMO International Maritime Organisation.

(Global Maritime Distress and Safety System)- The Global Maritime Distress and Safety System (GMDSS) is intended to provide more effective and efficient emergency and safety communications and disseminate Maritime Safety Information (MSI) to all ships on the world's oceans regardless of location or atmospheric conditions. MSI includes navigational warnings, meteorological warnings and forecasts, and other urgent safety related information GMDSS goals are defined in the International Convention for The Safety Of Life At Sea (SOLAS). The National Weather Service participates directly in the GMDSS by preparing meteorological forecasts and warnings for broadcast via NAVTEX and SafetyNET.
