![]() ![]() Discussions currently underway at ITU aim to make the GMDSS more flexible in terms of maritime safety information distribution, which in turn should open the door to new technology applications in this area, said Medici.ĭigital selective calling (DSC), for example, which enables a radio station to establish contact with and transfer information to another station or group of stations, enhances maritime safety. Modernizing the GMDSSĭistress, safety, and emergency maritime communications are coordinated through the Global Maritime Distress and Safety System (GMDSS), which uses terrestrial communication and satellite systems (such as those operated by Inmarsat and Iridium) to connect ships and coast stations. ITU Recommendations, Reports, Regulations, and databases – along with giving seafarers vital information – help safeguard the frequency bands that vessels use to navigate safely, as explained by ITU’s German Medici at the World Radiocommunication Seminar (WRS-22) in October. By extension, they utilize the naturally limited radio frequency spectrum.Īlthough the International Maritime Organization (IMO) develops regulations for shipping, ensuring safe maritime communication largely falls to the International Telecommunication Union (ITU). ![]() All these systems rely on some form of radiocommunication. Search and rescue aircraft also form part of this ecosystem of global maritime safety resources. These include ship stations (meaning radiocommunication equipment on board commercial, passenger or patrol vessels, etc.) coast stations that support ships at sea as well as radar services, automatic identification, and maritime distress systems. Much of the world’s commerce would simply not be possible without the plethora of technologies making up today’s maritime communications ecosystem. Vital commodity flows, as well as seafarer safety, hinge on ever more sophisticated maritime communication networks. An estimated 90 per cent of the goods traded around the world travel by sea. ![]()
