What is NAVTEX

NAVTEX is a system for the broadcast and automatic reception of maritime safety information by means of a narrow-band, direct-printing telegraphy. NAVTEX provides shipping with navigational and meteorological warnings and urgent information through automatic printouts from a dedicated receiver.

How does it Work?

NAVTEX transmissions are sent via a double frequency from localized stations situated worldwide. The power of each transmission is regulated so as to avoid the possibility of interference between transmitters. Users can set their NAVTEX receivers to receive specific message types and reject others.

Messages such as navigational and meteorological warnings and search and rescue information are non-rejectable to ensure that ships equipped with NAVTEX always receive the most vital information.

NAVTEX - Navigational Warnings by Telex

NAVTEX - Germany

Schnoor Industrieelektronik has installed a NAVTEX broadcast station for the German Weather Service (Deutscher Wetterdienst) in Pinneberg (in the middle of Schleswig-Holstein). The transmission power of 1000 W is radiated by a 99 meter high antenna to obtain coverage of more than 300 kilometres.

The international messages are transmitted on 518kHz in English and the national messages are transmitted on 490kHz in German language.

The main and the auxiliary transmitter are remotely controlled in start and end of transmission and data to be send out. Additionally, the user has the possibility to change remotely the frequency of the transmitter. This is necessary if an urgent message has to be sent.

If an error occurs, the main transmitter will shut down and the auxiliary transmitter goes on with the transmission.
