Maritime safety information
||It has been suggested that this article be merged into Global Maritime Distress and Safety System. (Discuss) Proposed since December 2013.|
Maritime safety information (MSI) is information that is broadcast to mariners by official agencies for their safety. Maritime safety messages consist of messages such as weather warning, warnings about dangers to navigation and failure of navigation devices.
These messages are broadcast over the Inmarsat satellites, the Navtex broadcast system, and various radio telephone systems as well as the international high frequency narrow band direct printing service. For the purpose of distributing this information the world is divided into NAVAREAS where information from official providers is filtered before being broadcast on the system to mariners.
