The review and modernization of the Global Maritime Distress and Safety system (GMDSS) continues this week at the fourth session of the Sub-Committee on Navigation, Communications and Search and Rescue (6-10 March). The GMDSS requirements in SOLAS Chapter IV were adopted in 1988 and ensure an integrated communications system using satellite and terrestrial radiocommunication systems. The meeting is expected to develop a draft modernization plan for the GMDSS for approval by the Maritime Safety Committee (MSC). The meeting is also expected to prepare draft amendments to SOLAS to accommodate additional, global or regional, mobile satellite systems. There are several agenda items related to e-navigation. Also on the agenda are: the technical review of proposed new or amended ships' routeing measures; the functioning and operation of the Long-Range Identification and Tracking (LRIT) system; and search and rescue related matters, including the harmonization of aeronautical and maritime search and rescue. IMO Secretary-General Kitack Lim opened the session, which is being chaired by Mr. Ringo Lakeman (the Netherlands). (Click for photos)
