GMDSS Radio Survey Blog

The Global Maritime Distress and Safety System (GMDSS) is a globally accepted and adopted set of rules protocols and prescriptions, which assure safety navigation and shipping. The GMDSS equipment is applied to increase safety and make it easier and faster to rescue distressed ships, boats and aircrafts. The GMDSS enables a ship in distress to send an alert using various radio systems. Thanks to this system the alerts has a very high contingency to be received by either shore rescue authorities and/or other vessels in the area.

Since the invention of radio at the end of the 19th century, ships at sea have relied on Morse code, invented by Samuel Morse and first used in 1844, for distress and safety telecommunications. But this mean appeared difficult and not reliable enough to assure the safety at sea in full volume.
