The Global Maritime Distress Safety System (GMDSS) is an internationally agreed-upon set of safety procedures, types of equipment, and communication protocols used to increase safety and make it easier to rescue distressed ships, boats and aircraft.

GMDSS consists of several systems, some of which are new, but many of which have been in operation for many years. The system is intended to perform the following functions: alerting (including position determination of the unit in distress), search and rescue coordination, locating (homing), maritime safety information broadcasts, general communications, and bridge-to-bridge communications. Specific radio carriage requirements depend upon the ship's area of operation, rather than its tonnage. The system also provides redundant means of distress alerting, and emergency sources of power.

Recreational vessels do not need to comply with GMDSS radio carriage requirements, but will increasingly use the Digital Selective Calling (DSC) VHF radios. Offshore vessels may elect to equip themselves further. Vessels under 300 Gross tonnage (GT) are not subject to GMDSS requirements.

Components of GMDSS

The main types of equipment used in GMDSS are:

A. Most maritime officers have a GMDSS license. Study the question pool (which is available online), as the exam is multiple-guess, and once you understand how the questions are framed, it'll be easier to get the answers. Unless you're planning on becoming a certified radar repair tech, don't go crazy with studying- 90% of the GMDSS material is useless in the modern era. You don't need to know about quarter-v-half round antennas and such. One other thing: GMDSS marine stations as they exist on ships are damn-near useless, because of misuse by ill-trained marine officers from Pakistan, India, and just about all of africa, who send out or relay false distresses, thereby clogging traffic and rendering anything but an EPIRB useless for… [cont.]
