The Global Maritime Distress and Safety System (GMDSS) is a set of international standards established by the International Maritime Organization (IMO) to enhance the safety of maritime communication and navigation. This system integrates radio communication, satellite navigation, and emergency alert systems with the aim of providing effective and timely emergency communication and navigation services worldwide. Fully implemented since February 1, 1992, GMDSS is composed of a comprehensive global communication search and rescue network through satellite communication systems (such as INMARSAT and COSPAS SARSAT), land-based radio communication systems (coastal radio stations), and maritime safety information broadcasting systems.

Maritime mobile radios under GMDSS are essential equipment for daily communication and distress alerting on ships and maritime facilities. These radios must comply with the requirements of the International Convention for the Safety of Life at Sea (SOLAS) and have the following capabilities:

Distress Alerting: GMDSS radios can send and receive distress signals, ensuring that search and rescue organizations and other ships can be quickly notified in case of an emergency.

Search and Rescue Coordination Communication: During search and rescue operations, GMDSS radios are used for communication between the search and rescue coordination center and the ships involved in the search.

On-Scene Communication: GMDSS radios are used for communication during on-scene search and rescue operations, including coordination and information exchange between search and rescue vessels.

General Radio Communication: GMDSS radios are also used for routine radio communication, such as port operations and communication between ships.

Navigational Safety Information Broadcast: The GMDSS system provides navigational warnings, meteorological information, and other navigation safety-related information through radio broadcasts.

The equipment requirements for GMDSS maritime mobile radios vary depending on the type of ship and the operating area. For example, INMARSAT satellite mobile radios are commonly used on ocean-going vessels, while VHF (Very High Frequency) radios are widely used in coastal and offshore waters.

In summary, GMDSS maritime mobile radios are key equipment for maritime safety communication. They play a vital role not only in emergency situations but also in routine maritime communication. Through these devices, ships can maintain contact with coastal radio stations and other ships, ensuring the safety and efficiency of navigation.
