1. NAVTEX SYSTEM
1.1 NAVTEX introduction
NAVTEX provides shipping with navigational and meteorological warnings and urgent information
by automatic display and/or print out from a dedicated receiver.
NAVTEX is a component of the IMO/IHO World-Wide Navigational Warning Service (WWNWS) de-
fined by IMO Assembly resolution A.706(17), as amended, and the WMO Manual on Marine Mete-
orological Services, Part Ibis, Provision of warnings and weather and sea bulletins (GMDSS appli-
cation). It has been included as an element of the Global Maritime Distress and Safety System
(GMDSS).
The original NAVTEX specification allowed for equipment with integral printers and precluded the
fitting of equipment which relied on other ways of recording and displaying NAVTEX data.
The use of Liquid Crystal Displays and other Visual Display Units is now ubiquitous on ship’s bridges
and this revision of the specification allows for their use in displaying NAVTEX data.
IMO Resolution MSC.148(77) states that the equipment should comprise radio receivers, a signal
processor and:
either:
a) an integrated printing device; or
b) a dedicated display device, printer output port and a non-volatile message memory; or
c) a connection to an integrated navigation system and a non-volatile message memory.
International NAVTEX services, refer to the frequency of 518kHz, and through international co-ordi-
nation to broadcast and automatically receive the maritime safety information in English language.
Domestic NAVTEX services, refer to the authority-specified frequencies 490kHz and 4209.5kHz, to
broadcast and automatically receive the marine safety information in a national language.

1.2 NAVTEX principle
For navigation purposes, the world is divided into 16 areas as shown in the figure below. Each
NAVTEX station has an identification code, from the A to Z. The frequency assigned to NAVTEX are
518 kHz , 490 kHz and 4209.5 kHz, and many stations exist in the same service coverage.
If the stations were to transmit without any rule, the system would collapse due to mutual interference.
To avoid this problem, the following rules apply.
- The transmission schedule is determined so that two or more stations having a common service
area may not overlap in time.
- Each station transmits with minimum required power to cover its service area (200 to 400 nau-
tical miles nominal).

1.3 NAVTEX message format
For automatic identification of NAVTEX messages, each message has its ID No which is identified
as B1, B2, B3 and B4 to indicate origin, category and serial number of the message.
- Character B1 is the identification letter of the NAVTEX station “A” to “Z”.
- Character B2 indicates the type of message “A” to “Z”, as listed in [Table 1-1].
- Character B3 and B4 indicate the serial number of the message. The serial numbers are
counted up from “01” to “99”, and starts from “01” again. “00” is specially reserved for important
emergency messages.
The end of each message is indicated by “NNNN” (four successive N’s).
General message format is summarized below.
