PRINCIPLE OF NAVTEX SYSTEM

How 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.

NAVTEX 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. PRINCIPLE OF NAVTEX SYSTEM

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 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 Ns). General message format is summarized below.

Header code ZCZC Start code (sync) B1 B2 B3 B4 main message Main message NNNN Termination code
Serial number "00": Emergency message "01" - "99": Normal message Type of message "A" - "Z" (See the list below.) Station ID "A" - "Z"

NRM: NAVTEX receiver mask
This command is used to manipulate the configuration masks that control which messages are stored, printed and sent to the INS port of te NAVTEX receiver. $--NRM,x,x,hhhhhhh,hhhhhhh*hh<CR><LF>
message type mask (SEE NOTE 4)
transmitter coverage area mask (SEE NOTE 3) frequency table indes, 1 to 9 (SEE NOTE 2) function code, 0 to 9 (SEE NOTE 1) NOTE 1: The function code is used to further identify the purpose of the sentence. The meaning of the function code is as follows: 0 - request messages for the given mask 1 - set/report the storage mask 2 - set/report the printer mask 3 - set/report the INS mask 4 to 9 - reserved for future use NOTE 2: The frequency indicator identifies the frequency that the NAVTEX message was received on: 1 = 490 kHz 2 = 518 kHz 3 = 4209.5 kHz 4 through 9 are reserved for future use NOTE 3: The transmitter coverage area mask is defined as a 32 bit hex field where the least signification bit represents transmitter coverage area "A", the next bit is "B" and so on up to bit 25 which is "Z". Bits 31 through 26 are reserved for future use and are set to zero. To select a transmitter coverage aera, its corresponding bit should be set to one. To deselect a transmitter coverage area its corresponding bit should be set to zero. NOTE 4: The message type mask is defined as a 32 bit hex field where the least significant bit represents message type "A", the next bit is "B" and so on up to bit 25 which is "Z". Bits 31 through 26 are reserved for future use and are set to zero. To select a message type its corresponding bit should be set to zero. When another device (for example an INS) wishes to set one or more of the bit masks it sends one or more NRM sentences to the NAVTEX receiver. When another device wishes to determine the current values of the bit masks it sends a query sentence to the NAVTEX receiver as follows: $--CRQ, NRM*hh<CR><LF> On receiving this query, the NAVTEX receiver will respond with one NRM sentences for each mask type and frequency combination that it supports. For example a NAVTEX receiver which support separate storage, printer and INS masks for each of three receiver frequencies will return a total of nine NRM sentences in response to the above query. Example $INNRM,2,1,00001E1F, 00000023*57 This example specifies that message identifiers "A", "B" and "F", received from transmitter areas "A" to "E" and "J" to "M" on 490 kHz should be sent to the printer port when they are received. Note that this command sets the printer mask for future use; there is no immediate output generated as a result of receiving this command. Example $INNRM,0,2,00001E1F,0FFFFFF*21 This example requests that all currently stored messages of all message type, received from transmitter areas "A" to "E" and "J" to "M" on 518 kHz should be immediately returned to the requesting device as a series of NRX sentences. Note that this command does not update any of the stored masks.

Output data description NRX: NAVTEX received message
NOTE 1: The total number of sentences required to transfer the NAVTEX message from the NAVTEX radio receiver. The first field specifies the total number of sentences used for a message, minimum value 1. The Sentence Number field identifies the older of this sentence in the message, minimum value 1. All sentences contain the same number of fields. For efficiency it is recommended that null fields be used in the additional sentences where the data is unchanged from the first sentence (this applies to fields 4 through 12). NOTE 2: The sequential message identifier provides a unique identifier for each NAVTEX message represented by a group of sentences. Though the message code (field 4) contains a NAVTEX message serial number, there are special cases when the message serial number is set to 00 and has a different meaning or when the same message code can occur more than once. When these conditions occur, the sequential message identifier can be relied upon to uniquely identify this NAVTEX message from other NAVTEX messages with the same message code. NOTE 3: The NAVTEX message code contains three related entities. The first character identifies the transmitter coverage area and the second character identifies the type of message. Both these characters are as defined in Table I of Recommendation ITU-R M.625-3, combination numbers 1-26. Transmitter identification characters are allocated by the IMO NAVTEX manual (IMO publication 951E). The remaining two characters are restricted to numerals with a range of 00 to 99 and represent a serial number for each type of message. The value of 00 is a special case and not considered a serial number. NOTE 4: The frequency indicator identifies the frequency that the NAVTEX message was received on: 0 = not received over air (eg test messages) 1 = 490 kHz 2 = 518 kHz 3 = 4209,5 kHz 4 through 9 are reserved for future use NOTE 5: The total number of characters indicates the expected size of the message body sent in this sequence of NRX sentences. It does not include the additional overhead for reserved characters found in table 1 of IEC 61162-1. NOTE 6: Status A is used for syntactically correct message reception. Status V is used for syntactically incorrect message reception, e.g. end characters NNNN missing. NOTE 7: The message body may contain reserved characters as defined in IEC 61162-1.

NAVTEX system operation

The world is divided into 16 areas (called Navareas) as shown at right. Each Navarea has multiple NAVTEX stations and each NAVTEX station has an identification code, from A to Z. The service range of a NAVTEX station is typically 200-400 nautical miles depending on the terrain and station transmit power. A NAVTEX station normally broadcasts every four hours. There are two channels including international channel, 518 kHz, and local channels, 490 and 4209.5 kHz. International channels broadcast messages in English. On local channels, 490 kHz, is available in the UK, France, etc., using their own languages. 4209.5 kHz is allocated for NAVTEX broadcasts in tropical areas - not widely used at the moment.

TRADE MARK REGISTERED MARCA REGISTRADA
FURUNO NX-700 is a dual-channel NAVTEX receiver for SOLAS ships complying with the new NAVTEX performance standard MSC.148(77) which is implemented on and after 1 July 2005. The NX-700 can receives two channels simultaneously. One is set for 518 kHz to receive international NAVTEX messages and another is selectable from 490 or 4209.5 kHz for domestic or local NAVTEX messages. These messages include a variety of safety information such as Navigational Warnings, Meteorological Warnings, Search and Rescue (SAR) information and other information for ships sailing within the reach of each service stations coverage. The broadcast station can be selected automatically according to own ship position when the NX-700 is connected with a GPS navigator.
Enhances the navigation efficiency and safety by watching NAVTEX messages broadcasted on both international and local channels

Every incoming message is stored in non-volatile memory and is displayed on the clear 5" silver bright LCD. Three different font sizes are available and one of them can be selected on menu. The NX-700-A consists of a receiver, display with printer and antenna units. The NX-700-B has a low profile, stylish display without a printer, receiver and antenna units. The compact umbrella type antenna requires no grounding because it is H-field antenna. In addition, the antenna incorporates a high-performance preamp within the compact body, which gives reliable and uninterrupted reception without an extra whip antenna.

Message inbox

Status icons Message icons
All received messages with a selected channel information are sorted by order of time in the message inbox. Operators can easily know the status of each message from the message ID and icons. When receiving SAR information, NX-700 notifies of the incoming messages by audible alarm. For quick viewing, operators can pick up messages they are interested in and display them by using the sort function.
