Description
The 2024 edition of the GMDSS Manual incorporates the most up-to-date developments from the IMO’s GMDSS modernisation project, completed in 2022. This major initiative led to a comprehensive revision of relevant SOLAS regulations and numerous related IMO instruments—both mandatory and non-mandatory.
This edition includes:
- A clear introduction to the GMDSS and an overview of its underlying concept
- Descriptions of GMDSS components, carriage requirements, and operational procedures
- In-depth coverage of terrestrial and satellite-based radiocommunication systems used within the GMDSS
- Updates on ongoing IMO work concerning future radiocommunication systems and services
- Guidance on the dissemination of maritime safety information and search and rescue alerts, including NAVTEX and Enhanced Group Call services
- Key excerpts from SOLAS regulations relating to the GMDSS
- Relevant supporting IMO resolutions
- The current GMDSS Master Plan, detailing coastal infrastructure and services provided by IMO Member States
- Selected extracts from the ITU-R Radio Regulations outlining the regulatory framework
This manual is a vital reference for ship personnel, shore-based operators, trainers, maritime administrations, regulators, and anyone involved in maritime radiocommunications.
