Radio Survey

Communication Systems in the Maritime Industry

Category: GMDSS Radio

Marine communication has long history and continues developing to this day. For the last years this field have been changed and innovated greatly. 

At the first stages of its evolution semaphores and flags were used, later mariners began using radio for transmitting distress signals and also Morse code was in practice.


Only in the second half of twentieth century IMO brought in an automated system of ship-to-ship or ship-to-shore communication and the constant presence of marine officer wasn’t necessary any more. 

Such communication was held by means of on board systems through the shore stations and satellites. Thus ship-to-ship communication was carried by VHF radio, and then DSC appeared. It could provide digitally remote control commands to receive and transmit distress signals, urgent calls and current messages. Today DSC controllers can be combined with VHF radio.
