DNV GL has brought the latest agreements from the recent 7th session of the IMO’s Sub-Committee on Navigation, Communications and Search and Rescue (NCSR) to the attention of the shipping community.

The meeting agreed, among other decisions, to recognise the Indian Regional Navigation Satellite System (IRNSS) for the provision of positioning, navigation and timing services, agreed to develop a generic performance standard for satellite radionavigation systems, and finalised draft SOLAS amendments for the modernisation of the Global Maritime Distress and Safety System (GMDSS).

NCSR 7 agreed to develop generic performance standards for satellite radionavigation systems (global or regional). The work will combine the many performance standards for receiver equipment into one document .

The Global Maritime Distress and Safety System (GMDSS), adopted in 1988, has been subject to review and modernization to adapt to modern communication systems and remove carriage requirements for obsolete systems. NCSR 7 finalised draft amendments to SOLAS Ch. III and IV on radiocommunications for modernisation of GMDSS.

NCSR 7 further identified 40 IMO resolutions and circulars in need of consequential amendments and/or editorial treatment due to the changes to GMDSS. SOLAS amendments to accommodate additional mobile satellite providers entered into force on 1 January 2020, while NCSR 7 preliminarily assessed the Chinese BeiDou Message Service System (BDMSS) for use in the GMDSS and invited the International Mobile Satellite Organization (IMSO) to conduct the technical and operational assessment of BDMSS and to provide a technical and operational assessment report for consideration by a future NCSR session.
