While INMARSAT gives the scope of two way communications, the Corpas Sarsat has a system that is limited to reception of signals from emergency position and places with no facilities of two way marine communications, indicating radio beacons (EPIRB).įor international operational requirements, the Global Maritime Distress Safety System (GMDSS) has divided the world in four sub areas. These marine communication services are provided by INMARSAT (a commercial company) and COSPAS – SARSAT (a multi-national government funded agency). Satellite services, as opposed to terrestrial communication systems, need the help of geo-stationary satellites for transmitting and receiving signals, where the range of shore stations cannot reach. DSC controllers can now be integrated with the VHF radio as per SOLAS (Safety Of Life at Sea) convention. While ship-to-ship communication was brought about by VHF radio, Digital Selective Calling (DSC) came up with digitally remote control commands to transmit or receive distress alert, urgent or safety calls, or routine priority messages. Marine communication between ships or with the shore was carried with the help of on board systems through shore stations and even satellites.

In the seventies, after considering the studies of the International Telecommunication Union, IMO brought about a system where ship-to-ship or ship-to-shore communication was put into action with some degree of automation, wherein a skilled radio officer keeping 24×7 watch was not required.

Radio telegraphy using Morse code was used in the early part of the twentieth century for marine communication.

After the days of semaphores and flags (which is still relevant today in some cases), radio brought about a drastic change in marine communication at sea.įrom the early years of the last century, ships started fitting radio for communicating distress signals among themselves and with the shore. Radio telecommunication at sea had undergone a sea change in the last century.
