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)
defined by IMO Assembly resolution A.706(17), as amended, and the WMO Manual on Marine
Meteorological Services, Part Ibis, Provision of warnings and weather and sea bulletins (GMDSS
application). 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-ordination 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 and another (490 or 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
nautical miles nominal).

1.3 NAVTEX message format
For automatic identification of messages, each message starts with nine control characters, called
“Header codes”. The first five characters are always “ZCZC”and common to all messages. This
part is used for message synchronization. The latter four characters are designed 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”thru “Z”.
- Character B2 indicates the type of message “A”thru “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. The format of all messages is set according to
[Figure 1-3 NAVTEX Standard format for NAVTEX messages].

3. NVX-1000 SPECIFICATIONS
3.1 Software characteristics
3.1.1 B1 and B2 characters
The B1 characters identifying the different transmitter coverage areas and the B2 characters
identifying the different types of messages are defined by IMO and chosen from table I of ITU-R
Recommendation M.625, combination numbers 1-26.
a) NVX-1000 is capable of automatically rejecting unwanted information using character B1.
b) NVX-1000 is capable of disabling display of selected types of messages using character B2
with the exception of messages with B2 characters A, B, D and L.
3.1.2 B3 and B4 characters
B3 B4 is a two-character serial number, starting with 01 except in special cases where the serial
number 00 is used.
3.1.3 Preamble
Message store is only being activated if the preamble B1 B2 B3 B4 is received without errors.
3.1.4 Repetition of display
Facilities are provided to avoid printing, storage or display of the same message several times on
the same ship, when such a message has already been satisfactorily received.
The necessary information for these measures is deduced from the sequence B1 B2 B3 B4.
3.1.5 Mandatory display
A message shall always be stored and displayed if B3 B4 = 00 and if it is transmitted by a coast
station that the equipment is programmed to select. The characters ZCZC B1 B2 B3 B4 need not be
displayed.
3.1.6 Reception of messages with character errors
3.1.6.1 Messages with character error rate of > 4% and ≤ 33 %
NVX-1000 stores the message, but will allow the message to be replaced if it is subsequently
received with lower error rate.
NVX-1000 will display the test messages indicating a character error rate of ≤ 33 %.
3.1.6.2 Messages with character error rate of > 33 %
NVX-1000 will not store messages if the received character error rate > 33%.
3.1.7 Alarms
The receipt of search and rescue information (B2 = D) will give an alarm from NVX-1000. It is only
be possible to reset this alarm manually.
NVX-1000 contains an integral alarm buzzer or/and a pair of relay contacts for the provision of an
external sounder.
The alarms provided at NVX-1000 indicate, A\B\L messages and any messages, and it can be
suppressed by setting in menu.
3.1.8 Test facilities
NVX-1000 is provided with a facility to test that the radio receiver, the display device and
non-volatile message memory are functioning correctly.
