NAVTEX is designed to provide international automated direct-printing service such as
promulgationcom		of SAR (Search and Rescue) information, Navigational warnings, Meteorological
juxiangdianzi	.

warnings and urgent information to ships. It has been developed to provide a low-cost, simple and automated means of receiving maritime safety information for on board ships at sea and in coastal waters. The information transmitted by NAVTEX coast station, is delivered to each ship directly. On the bridge, the NAVTEX receiver accepts, selects information required for the ship and displays in LCD automatically in English or Korean mode as following [Figure 1-1]

international English broadcasting and [Figure 1-2] Korean broadcasting. NAVTEX means the
28631117
system for broadcast and					automatic reception of maritime safety information by means of
narrow-band direct-printing telegraphy and it is a component of IMO(International Maritime
Organization)/IHO(International Hydrographic Organization) WWNWS World Wide Navigational

become part of the mandatory equipment										which is required to be carried in certain vessels under
							Convention for the Safety of Life at Sea(SOLAS), 1974, as
the provisions of the International
amended in 1988.
	This system provides International and National service as follows.

1.International NAVTEX service means the coordinated broadcast and automatic reception on frequency 518kHz of maritime safety information (MSI) by means of narrow-band

direct-printing telegraphy using the English language.

2.National NAVTEX service means the broadcast and automatic reception of maritime safety information by means of narrow-band direct-printing telegraphy using 490kHz or 4209.5kHz frequencies other than 518kHz as decided languages by the Administrations concerned.

www	.

	com
NAVTEX service uses a single frequency for transmissions from nominated stations within
each.	NAVAREA being arranged on a time-sharing basis to eliminate mutual interference as
juxiangdianzi
following [Figure 1-4].

All necessary information is contained in each transmission. The power of each transmitter is regulated so as to avoid the possibility of interference between transmitters. It may be adjusted to provide a range of about 250 to 400 nautical miles.

28631117But certain essential classes of safety information such as navigational and meteorological

according to a technical code(B1, B2, B3, B4), which appears in preamble of each message and
whether or not the particular message has already been printed.
warnings
	and search and rescue information									are non-reject able to ensure that ships using
NAVTEX	always receive the most vital information.
According to [Figure 1-3] of the NAVTEX concept, NAVTEX coordinators exercise control of
messages transmitted by each station according to the information contained in each message
and the geographical coverage required. Thus a user may choose to accept messages, as
appropriate, either from the single transmitter which serves the sea area around his position or
from a number of transmitters.

juxiangdianzi

The format of all messages is set according to [Figure 1-6]. This defines essential elements of

the message that influence the receiver to be operated.

Great care is required to avoid errors of syntax in the groups ZCZC, B1B2B3B4, and NNNN as

they will cause receivers operate incorrectly, and may well result in the loss of vital message.

1.4 Message numbering . com juxiangdianziAccording to [Figure 1-6] of Standard format for NAVTEX messages, each message within a

subject group is allocated a serial number, B3B4, between 01 and 99. This number should be allocated by the relevant NAVTEX coordinator.

Certain message is allocated [the B3B4 = 00]. Use of this number should be strictly controlled

since messages carrying it will always be displayed in LCD screen, if the broadcast containing

such messages is identified to accept by the receiver. Therefore, the number "00" must only be

used for severely important messages, such as an initial distress message. Routine messages

28631117

and service messages should not be allocated to the number “00”.

All message numbers including "00", are stored in the memory always.
