Answer:
OVERVIEW
Maritime transport is the backbone of international trade. Around 80% of the world's merchandise is transported by sea and handled by ports, so safe navigation is vital for the ships' crews, as well as the global economy. For decades, ships' captains have depended on radio as means for necessary communication and navigation – to declare their travel intentions, share their positions and avoid collisions. Radio must work seamlessly to ensure safety at sea.
Today, mariners use radio, radar and electronic systems and satellite navigation to determine accurately the position of their vessel and that of other vessels, to ensure safe navigation. They also make use of radiocommunications for operational use as well to contact family and loved ones, and radio distress signals to alert search and rescue services in the event of an emergency.
ITU has contributed to key developments in terrestrial radio navigation systems, including maritime radio beacons, terrestrial positioning systems in the medium frequency (MF) bands, and radar beacons as well as satellite positioning systems to enhance safety at sea.
Radiocommunication contributes to United Nations Sustainable Development Goal 9 (Industry, Innovation and Infrastructure) by enhancing safety, security and comfort at sea.
