NAVTEX fulfils an integral role in the global maritime distress and safety system (GMDSS) which has been developed by the International Maritime Organization and contributes to the safety of life at sea.
The NAVTEX system is commended to Administrations having responsibility for maritime affairs and to mariners who require an effective maritime safety information service. This manual is intended for use by seafarers, shipowners, maritime Administrations and others concerned with the preparation, broadcasting and receiving of maritime safety information.
