What Is NAVTEX?

What Is NAVTEX?

What Is NAVTEX?What Is NAVTEX?

NAVTEX is a worldwide system for the broadcast and automatic
reception of mari time safety information ( MSI ) i n Engli sh by m eans
of a narrow-band direct-printing telegraphy. NAVTEX provides
shipping with navigational and meteorological warnings and urgent
information.

NAVTEX is a component of the IMO/IHO worldwide Navigational
Warning Service (WWNWS) as defined by IMO Assembly resolution
A.706(17). It i s i ncl uded within the Global Maritime Distress and
Safety System (GMDS S ). Si nc e 1 August 1993, NA V TEX receiving
capability has become mandatory equipment for certain vessels
under the provi si ons of the International Convention for the Safety of
Life at Sea (SOLAS).

NAVTEX broadcast i nformation is available to all seafar er s, free of
charge.

NAVTEX transmi ssions are sent from stations situat ed worl dwide.
The power of each transmi ssion is regulated so as to avoid the
possibili ty of interference between transm itters. Each station is
allocated a 10-mi nute time slot every 4 hours so that many stati ons
can share the same frequenc y . Stations typically hav e a
transmi ssion range of 250 – 300 Nm.

The messages currentl y displayed are a sub-set of all the messages
stored in memory. Whet her y ou c an see a particular message or not
depends upon the current station selection, message fi lter and age
limit setti ngs (see following sections for details).

Message Storage

All received NAVTEX messages are stored in m em or y regardless of
whether you have them sel ected for viewing or not. The Nav6plus
has lots of memory so you will easily have enough storage for all
messages received in any 72 hour period. The messages displayed
are selected fr om the Nav 6plus’ memory by applying the current
message filter pr eset & age limi t sett ings. This enables you to
change your mind later about your message display options. This
means you will still be able to view messages that were received
previously, but were not selected for display at t he time, by c hanging
the current m essage fil ter or age setting.

After using the Nav6plus for a while you may notice that if you
receive a particular message more than once there will only ever be
one copy in view. If a message has been received more than once
the Nav6plus will stor e only the best version. It even attempts to
repair corr upted messages using comparing copies of the same
message!

Filter Presets

The messages currentl y av ailable for viewing on screen are selec ted
from the messages stored i n m em or y by applying ‘filter presets’.

To see the current sel ected filter presets go to [Navtex Mode⇒⇒⇒⇒Filter
View]. You will noti c e that the left hand softkey is labelled ‘Pr eset’
and a number from 1 to 5 is visibl e. Thi s is the cur r ently selected
filter preset number for the this ‘filter page’. E ac h of t he 4 filter pages

filter preset number.
Select the preset that you require for the filter page t hat you are

viewing and then look at the presets for the other filter pages. Note
that the preset that i s di spl ay ed is the one that is currently applied to
the message display.

Multiple presets can be used for switching quickly between different
sets of messages on the screen. For instance, if you want to show
just ‘navigational warnings from all stati ons i n r ange’, you can use a
preset to do this.

Although the pr eset s are pre- pr ogr am med, you can set them to any
filter setting you require.

Tip : Use preset 1 for normal operat ion and only us e the other
presets if you want to switch between different sets of mes s ages on
the display.

Station Selection

If you leave your Nav 6plus receiving for 72 hours you will have
received many messages (subj ec t to your current location) and
unless you filter out those stations that are not required for display,
you will be swamped with data. This can either be done
automatic all y usi ng a GPS or by using manual filter settings. In eit her

case go to [Navtex Mode⇒⇒⇒⇒Filter View⇒⇒⇒⇒490 or 518 Stns Page]. You
will notice t hat each station can be set to one of three filter settings:

Setting Operation

On Messages from station always in view (see note 1)
Off Messages from station never in view
Auto Messages from station only viewed when nearest or in

range depending upon setting (see note 1)

note 1 : messages are only displ ay ed if they also fall within the
ageing limit, er ror limit and message category filter settings.

An asterisk to t he ri ght of the station name indicates that t he station
is selected with the current filter setting.

Automatic Stat ion S elec tion Using GPS

Many users will j ust want t o displ ay NA VTE X from the nearest
NAVTEX station to their cruising location. This is most easily
achieved by connec ting a GPS and selecting ‘Nearest’ stati on option
in the set up page.

With a GPS connected and ‘Nearest’ sel ec ted you should only see
one (or sometimes two) asterisks. Ensure that the set of stations that
you want to automatic ally select from are all set to Auto. Stations
that you definitely do not want should be set to Off. You may wish to
set your ‘home’ stati on to On so that you display messages from it
even if it is currentl y not t he near est station to your cruising posi tion.

Manual Station Selection

Alternatively, you can manually select a station ( or st ations) setting
stations to On or Off by using t he
If you are using a GPS but still want t o sel ec t stat ions manually then
do not leave any stations set to Auto.

Message Filtering

You can further reduce the amount of unwanted messages that are
displayed by applying a filter to the message categories. Go to
[Navtex Mode, Fil ter View, 490 or 518 Types Page]. Each message
category can be turned On or Off or can be set to New using the

DOWN, LEFT & RIGHT keys.

Reading ‘New’ Messages

Sometimes it i s usef ul to know which messages have been received
since you last looked at the Nav6plus display. You may hav e noticed
that each message header carries a ‘NEW’ icon and that there is an
additional ‘NEW’ icon in the status bar at the top of the display .

Select [Navtex Mode⇒⇒⇒⇒Message View] and you will see that what
was the
message at the top of the displ ay has the ‘NEW’ icon showing then
the left hand softk ey will now be indicated as
you have read the message & want to de- em phasi se i t then press
MARK READ. The ‘NEW’ icon will disappear fr om the message
header. Press
Proceed through all of the messages in this way. Once all of the
messages have been mark ed as read t hen the ‘NEW’ icon at the top

11

Nav6 Plus Navtex System User Guide

later on it is now very easy to tell if there are any new messages to
read (the ‘NEW’ ic on in the stat us bar at the t op of t he displ ay will be
illuminated).

Note that messages that have been ‘marked as read’ will still be
displayed but with the ‘NEW’ icon removed from the header in eac h
one. However, it is possible to hide messages once they have been

read. Go to [Navtex Mode ⇒⇒⇒⇒Filter View⇒⇒⇒⇒490 or 518 Types Page]
and set the message categories that you want to hide after they
have been marked as read t o ‘New’ instead of ‘On’. You may wish to
leave SAR messages as ‘On’ so that t hey ar e not hidden once read.

Displaying The Newest Message

All messages are date and time stamped by the Nav6plus even if
there is no GPS connected and t her efore no correct source of time
data.

If there is not a GPS connected then you can manually enter the
time and date or just ignore it. The Nav6plus will still order the
messages in the cor r ect c hr onological order (remember t hat t he
indicated time of reception will be wrong though).

To display the newest message, go to [Navtex Mode⇒⇒⇒⇒Sort
View⇒⇒⇒⇒Descending Order⇒⇒⇒⇒Date Criteria]. The newest m essage is

now at the top of the displ ay.

Message Aging

NAVTEX messages become less relevant over time & eventuall y just
clutter the di spl ay . I n or der to r educ e the num ber of obsolete
NAVTEX messages that are being displayed, the Nav6plus uses the
concept of a message ‘Age Limi t’.

It is possible to hide messages that are older than a certain pr e­settable age limi t. These messages are still stored in the Nav6plus
memory for a considerable time after they have been removed from
the display and can stil l be displayed if necessary by increasi ng the
message age limit sett ing.

To change the age limit go to [Set up M ode⇒⇒⇒⇒Navtex View⇒⇒⇒⇒Options
Page] and select t he age limit that you require. Use the
DOWN key to select ‘age limit’ and LEFT & RIGHT keys to select a
value. 3 days is a sensible choice as NAVTEX messages have a
nominal lif e of 72 hours. S et a longer age lim it if you wish to display
NAVTEX messages going back over the previous weeks.

• The correct magnetic variation must be input at the navigation

instruments (e.g. GPS, electronic compass) for the accurate
display of COG, set, waypoint bearing and heading.

• For the purposes of testing your installation, you may wish to use

your GPS’s simulat or m ode to generate data for the Nav6plus.
Please check your GPS User Manual to find out whether it
transmits valid NMEA data whilst it is in its simulator mode –
many GPS’s do not set the ‘data v alid’ flag in the NMEA
sentences during simulation. As a safety feature, the Nav6plus
will ignore any NMEA sentences where the ‘dat a valid’ flag is not
set.

The Nav6plus can be confi gur ed to function like a GMDSS paper
Navtex printer when connected to a suitable serial printer. A Nav6
serial print er c an be purchased from ICS (ICS order number 918.00).
Alternatively, an ICS Nav4 Navtex receiver can be modified to
become a Nav6 serial printer by purchasing a Nav4 to Nav6 printer
conversion ki t (ICS order number 6100.00).

The Navtex auto pri nt f acili ty acts like a GMDSS paper Navtex
printer:

• Poor quality messages (error rates over 33%) are not pri nted.

• All new messages are print ed when first received.

• Only messages not excluded by the print filtering are printed.

• Message repeats are pri nted each time they are received until

they have been received with good quality (error rate of less
than 4%).

• Once a good quality message has been received, repeats are

not printed during the next 72 hours. After 72 hours the
message is treated as a new message and pri nted again.

The Navigation Log auto-print facility pri nts navigation log entries as
they are added to the Navigate Mode, Log View. Each log printout
contains time, date, position, COG, SOG, heading, water speed,
wind direction and speed, depth and distance. Only fi elds containing
valid data are pri nted.

INSTALLATION OF SENSOR UNITINSTALLATION OF SENSOR UNIT

The Sensor Unit is a rugged waterproof unit, but care should be
taken during installation to prevent damage t hat may lead to
subsequent water ingr es s.

• The Sensor Unit shoul d be m ounted so that the whip is

approximately vertical.

• The Sensor Unit can be screwed into a standar d marine antenna

rail mount (1" 14 tpi thr ead or ICS part number 903.03).

• The mounting posit ion should avoid any adjacent obstr uc tions

caused by the superstruct ur e etc.

• The Sensor Unit shoul d be loc ated at least 0.5metres away from

any other electr onic equipment including GPS antennas, Radar

• On a yacht, pushpit mounting is permissible.

Note: due to the variet y of pos s ible m ounting methods (horizontal
rail, vertical r ail, deck, etc) ICS do not supply the antenna m ounting
bracket as standard. They are readily available from m os t m ar ine
electronics st ores.

Mounting the Sensor Unit

Mounting the Sensor UnitMounting the Sensor Unit

• First, fix the antenna mount in the desired location.

• If required, thread the sensor cable through the antenna mount

(if the antenna m ount t hr ead has a slot to acc ept the sensor
cable mount this may not be necessary).

• Now fit the Sensor Unit on top of the antenna mount.

• Holding the top of the Sensor Uni t, rotate the large plastic nut on

the bottom in order t o engage the thread of the antenna mount.

• Continue to tighten the nut until the Sensor Unit is lock ed.

• Note that it is possibl e to position the Sensor Unit to face

whichever way the user desires.

• Do not use a wrench to tight en the nut – hand-tighten only.

care that potential tripping hazards are av oi ded.

• The Sensor Cable should be ti ed at regular intervals to ensure

that the cable is not c r ushed or able to vibrate as this may affect
its perform anc e.

• The Sensor Cable should not be bent through tight radii ( less

than 4cm ).

• Where the Sensor Cabl e passes through bulkheads or decking,

rubber gromm ets or the optional deck gland (ICS part number

For some install ations where local interf er enc e is thought to be
limiting rec eiver performance, it may be necessary to gr ound the
screen of the antenna cable.

Connect the screen of the interconnecting cable from the connecting
block to a good electri c al gr ound. This can either be a specially
installed ground plate, or the keel bolts on a non-encapsulated keel.

The Nav6 Navtex System shoul d be powered from a nominal 12Vdc
switched supply, c apable of providing a continuous 350mA .

• To allow the unit to be isolat ed for service, a 1.5A circuit break er
or a 1.5A fuse and switch should switch the power supply.

• Use the RED and BLACK twisted pair for connection to the
boat’s power supply.

• Connect the RED wire to boat’s positive (12V) supply.

• Connect the BLACK wire t o negative (0V) supply.

• Note that vessels that require isolation may need to install a DC

to DC converter (I CS part num ber 500.09) – if in doubt ask your
dealer.

• 24V vessels should i nstall the 24V / 12V DC to DC converter
(ICS part number 500. 10) .

Connecting an NMEA Source

Connecting an NMEA Source

Connecting an NMEA SourceConnecting an NMEA Source

• Use the BLUE and BLACK twisted pair for connection to the
NMEA data source.

• Connect the BLUE wire to the NMEA A signal.

• Connect the BLACK wire t o the NME A B signal.

(Trouble shooting: Note that NMEA signal terminology c an v ar y
between manufacturers – try swapping the BLUE and BLACK wires
if the NMEA input does not work initially – no damage will be done)

The Nav6 is compati ble with most sources of NMEA 0183 data such
as a GPS receiver or adapter box es supplied for use with networked
instrum ent systems. Please note that you may need to program the
source of NMEA data to send the cor r ec t sentences i n the correct
format. You may al so need to pur c hase an NMEA adapter box for
your instrument system. Should you be uncertain of your abil ities in
this area, you ar e strongl y adv ised to seek the services of a qualifi ed
marine elect r onic s i nstaller.

Note: We do not guarantee c om patibility with all GPS receivers or all
instrument systems. However, this can normally be achieved for
most systems by a skill ed installer. For notes on achieving
compatibilit y with various systems, see the Nav 6 FAQ secti on on our
web site: www.icselectronics.co.uk

The Nav6plus uses NMEA dat a for the following:

• To synchronise it s i nternal clock with UTC time.

• To display a wide vari ety of NMEA dat a in a selecti on of formats

(see Appendix IV for the NMEA sentences supported).

• To automatically filter the message display to show either

messages from onl y the near est Nav tex transmitting station, or
all stations that ar e c ur r ently within range.
