Features

NAVTEX (Navigational Telex) is a world wide coastal telex broadcasting system. Coastal NAVTEX broadcasting stations with specific ID’s transmit Navigational warnings. Meteorological warnings, Search and Rescue (SAR) information and other navigational information for NAVTEX receiver-equipped vessels sailing in coastal waters.

The FURUNO NX-700 NAVTEX receiver receives NAVTEX messages and automatically displays them together with station ID and message category information.

If ship’s position data is fed from navigation equipment, the NX-700 automatically decides in which NAVAREA the vessel is navigating, and selects stations. (NAVAREAs are geographical zones defined by the international Maritime Organization.)

1.PRINCIPLE OF NAVTEX SYSTEM

1.1How NAVTEX Works

NAVTEX is an acronym meaning Navigational Telex, and as its name shows, it is a kind of narrow band radio teletype system for sending (by frequency shift keying) text messages expressed in a 7-unit code. The difference is that a NAVTEX transmitter transmits nine control characters (header code) ahead of the main message, so that the receiver can identify the station, message type and serial number automatically.

1.2NAVTEX System Operation

For navigation purposes, the world is divided into 16 areas as shown in the figure below. Each Navtex station has an identification code, from “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).

1-1

1. PRINCIPLE OF NAVTEX SYSTEM

1.3Message 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 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 below. 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. Number “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.
