The International Association of Marine aids to Navigation and Lighthouse Authorities (IALA) has undertaken a comprehensive review of maritime radiocommunication systems. This contribution is intended to initiate a report on systems in the Maritime mobile radiocommunication service and their mode of operation.
This document is proposed as a replacement for Annex 19 to ITU-R Document 5B/167.
Maritime Mobile Radiocommunication service systems are involved in virtually all facets of modern maritime operations. On open ocean transits, while operating on inland waterways and in the logistical functions of ports these radiocommunication systems support safety and reliability. Systems critical to Global Maritime Distress and Safety System (GMDSS), to safety of life and safety of navigation are subject to specific maritime treaty requirements. New systems and applications continue to provide access to a wide range of other communication resources.
This is an extract of a larger IALA report on maritime communications.
The information presented is intended to support various ITU efforts to identify existing and evolving systems which support maritime radiocommunication services.
This Report is expected to beneficial to preparations for both WRC-15 and WRC-18.
“to consider regulatory provisions and spectrum allocations to enable possible new Automatic Identification System (AIS) technology applications and possible new applications to improve maritime radiocommunication in accordance with Resolution 360 (WRC-12);”
The purpose of this Report is to review existing maritime systems and build visions of future maritime communications technologies. Specifics will address emerging digital communications, navigational technologies, hydrographic matters and vessel traffic management.
