System Overview
The Navigation System is available in two configurations: GPS and DGPS. Both
configurations feature a Display. The GPS configuration also features a GPS
Navigation Sensor and an MGA-2 GPS antenna, while the DGPS configuration features
a DGPS Navigation Sensor and an MGL-4 combined GPS/Beacon antenna.
The Display provides a graphical interface to the system. Via the display it is possible
to create, edit and modify routes and waypoints, navigate following a route, plot the route,
view sensor data, perform setup as well as supervise the systems status.
The GPS Navigation Sensor features a high-precision GPS receiver, capable of
receiving WAAS, EGNOS and MSAS differential corrections. The DGPS Navigation
Sensor has all the features of the GPS Sensor, as well as a dual channel beacon receiver
for reception of IALA radio beacon DGPS corrections.
The Navigation Sensor is connected to the antenna, either an MGA-2 GPS antenna or
an MGL-4 combined GPS/Beacon antenna. The MGL-4 antenna is capable of receiving
and interpreting both radio beacon and satellite signals.
Together the Display and the Navigation Sensor provides three configurable serial
user ports, of which two are bidirectional and one used only for output of data. There are
also a binary Speed Log and an Alarm Output port, as well as an Alarm Acknowledge
input port.

CONCEPTS AND TERMINOLOGY
This chapter describes some of the commonly used terms of this Operator‘s Manual, and the
implied meaning when used in this manual.
Waypoint
A waypoint is a position on the earth's surface, represented by latitude and longitude, which
is given a unique name. A waypoint is typically used for navigation direct to a certain position
or as part of a route.
MOB Waypoint
A waypoint created when using the Man Over Board (MOB) functionality. The system can
store up to 20 MOB waypoints at the same time, if more are created the oldest one is
deleted. It is not possible to use MOB waypoints in routes.
Route
A route is a named, ordered sequence of waypoints, which together describes a path from
the start to the end waypoint. The route that currently is being sailed is called the active
route.
Active Route
The active route is the route currently being sailed and used for navigation. When starting to
sail a route, a copy of the route is made into the active route. Changes made to the active
route do not affect the source route, unless the active route is explicitly stored. Only one
route can be active at any point in time.
Leg
A leg is the segment of a route between two consecutive waypoints. A route with the
waypoints A, B and C has two legs: ―A to B‖ and ―B to C‖. For each leg in a route, the
navigation algorithm and RAIM accuracy level can be set.
RAIM
RAIM is a GPS integrity monitoring scheme that evaluates the quality of the position data
and is able (under normal circumstances) to detect a satellite malfunction that results in a
large range error.
RAIM Accuracy Level
The RAIM accuracy level is the radius that is used to calculate current RAIM status.
RAIM Status
The RAIM status can be one of safe, caution and unsafe, and is indicated by the LEDs on
the front of the Display.

SAA7000 109-143, H
Page 11
Navigation Algorithm
The navigation algorithm is the algorithm used for calculating the course to steer to reach the
next waypoint. It is also used for calculating the distance to the waypoint. The navigation
algorithm can be either great circle or rhumb line.
Great Circle Navigation
The great circle navigation algorithm calculates a course line that is the shortest path
between two points on the surface of the earth. Using this navigation algorithm, course to
steer when navigating towards a waypoint is not constant. The resulting track of this
navigation algorithm will differ from the straight line drawn on a Mercator projected chart.
Rhumb Line Navigation
The rhumb line navigation algorithm calculates a course line that corresponds to a straight
line on a Mercator projected chart, and cuts across all meridians at the same angle.
Waypoint Pass Criterion
The criterion used to determine when a waypoint in the active route is considered passed.
The waypoint pass criterion can be any of Manual, Distance, Bisector Line and Perpendicular
Line.
Manual Waypoint Pass Criterion
Using this pass criterion, the waypoint is only considered passed when the operator skips the
waypoint.
Distance Waypoint Pass Criterion
Using this pass criterion, the waypoint is considered passed once
the ship has reached an imaginary circle around the waypoint. See
illustration to the right. The radius of the circle is configurable.
Bisector Line Waypoint Pass Criterion
Using this pass criterion, the waypoint is considered passed once
the ship has reached an imaginary bisector line of the angle
between current and next leg. See illustration to the right.
Perpendicular Line Waypoint Pass Criterion
Using this pass criterion, the waypoint is considered passed once
the ship has reached an imaginary line perpendicular to current leg.
See illustration to the right.

The icons are also described in section 4.2 "Icon Description" on page 42 in the Reference
chapter.
3.4.2
RAIM Accuracy Level
The RAIM accuracy level specifies (in meters) the desired position accuracy used to
calculate current RAIM status. RAIM is a GPS integrity monitoring scheme that
evaluates the quality of position data and compares it to the specified accuracy level.
The LEDs on the front of the display will show the RAIM status. The green LED
indicates safe state; the calculated position accuracy is better than the set accuracy
level. The yellow LED indicates caution state; the system is unable to safely determine
if the position accuracy is better or worse than the set accuracy level. The red LED
indicates unsafe state; the calculated position accuracy is worse than the set accuracy
level. The LEDs and RAIM states are further described in section 4.1 "Status LEDs" on
page 41.
The used RAIM accuracy level is the latest specified accuracy level, either specified

Position
The Position view shows the last calculated position, speed over ground (SOG) and
course over ground (COG). The position shown is always the position of the
Navigation Sensor. The position is represented by latitude and longitude. Current time,
in UTC or local time, is also displayed. The view can contain four subviews, GPS
Status, Beacon Status, Satellite Information and Set RAIM. The Beacon Status view is
only present if an DGPS Navigation Sensor is used as the navigation sensor.
If the navigation system not is able to calculate new position information, the latest
valid information is shown in conjunction with the time when it was calculated. The
icon in the status bar will indicate that no new position information is available.
See section 4.2 ―Icon Description‖ on page 42 for further details on the icons.
Note: COG is based on track angle which requires that the ship is moving. Thus, COG
data is not displayed when the SOG value is below 0.3 knots.

The Set RAIM view is used to modify the used RAIM accuracy level. The RAIM
accuracy level is always set in meters. In the case the active route has RAIM
accuracies specified for any of its legs, a RAIM accuracy level specified in this view
will override the RAIM settings in the active route. If this is the case, you will be
warned before any RAIM level is set.
When overriding active route RAIM accuracy levels, the RAIM accuracy
level indication will appear underlined, as illustrated in the figure to the right.
When overriding, accuracy levels specified in the active route does not affect the

The Nav view presents fundamental navigation data and aids the user in navigating towards a waypoint and following a route. It presents information such as the bearing and
range to the next waypoint, the ship‘s current course over ground (COG) and speed
over ground (SOG) and current cross-track error (if sailing on a route). The view is also
an entry point to the three partially different subviews: Show Next Wp, Show ETA and
Show Wp Info. Show Next Wp shows a close-up plot of the next waypoint. Show Wp
Info shows the name of the active route, of the previous waypoint and of the current
waypoint. Show ETA shows current Estimated Time of Arrival to the end point of the
route as well as target ETA (if defined).
Note: COG is based on track angle which requires that the ship is moving. Thus, COG
data is not displayed when the SOG value is below 0.3 knots.

The rectangle in the lower part of the view visually represents current navigation information, as illustrated in the figure above. The difference between present course and
the course to head to exactly navigate towards next waypoint is illustrated by the
distance between the bold vertical bar and the center line. The bold vertical bar
represents current course and the center line represents the bearing to the next
waypoint. To steer towards the waypoint, make the bold vertical bar stand over the
center line. The rectangle can represent a course deviation of 30 .
If sailing on a route and having reached the first waypoint, the rectangle also presents
current cross-track error, illustrated by the distance between the boat symbol and the
center line. The cross-track error limit determines the scale of the rectangle; when the
boat symbol is outside the rectangle the cross-track error limit has been exceeded and
the XTE Limit Exceeded alarm will be raised (if enabled).

Tidal
The Navigation Display, software version 5.0.94 onwards, can be used for
calculation of tidal predictions based on user input of data from the Admiralty Tide
Tables published by the U.K Hydrographic Office.
The user is required to input data for the specific port and select the point in time for
which the prediction is to be calculated.
The tidal prediction features in the Navigation Display are centered around three
views; the Port List, Tide Plot and Tide Table views, available in the Plan Voyage
mode.
Note that meteorological effects (e.g wind and barometric pressure) as well as other
factors not accounted for in the generalized tidal models may cause significant
deviation between actual and predicted tide.
Operator Manual
REFERENCE
SAA7000 109-143, H
Page 104
4.9.6.1
Calculation Method and Source Data
The tidal predictions are calculated by the so called ‗simplified harmonic method‘.
Harmonic constants and other parameters required are included in publications
below. Note that the algorithms applied are specifically adapted for this data. Tidal
parameters obtained from other sources shall not be used with the Navigation
Display tidal calculations.
Predictions calculated according to this method will not be fully consistent with the
tabulated high/low and hourly predictions from the Admiralty tide tables. This is due
to the fact that the tabulated values are based on a more extensive data set
compared to the limited number of parameters used by the simplified harmonic
method
The source data is split between volumes with different geographical coverage as
follows:
U.K Hydrographic Office ADMIRALTY TIDE TABLES (ATT)
Volume 1 (NP 201):
United Kingdom and Ireland (including European
channel ports)
Volume 2 (NP 202):
Europe (excluding United Kingdom and Ireland),
Mediterranean Sea and Atlantic Ocean
Volume 3 (NP 203):
Indian Ocean and South China Sea
Volume 4 (NP 204):
Pacific Ocean
Optionally, for European ports, ATT Volume 1 and European part of Volume 2 can
be substituted by:
TIDAL HARMONIC CONSTANTS, EUROPEAN WATERS (NP 160).
4.9.6.2
Input of Tidal Parameters
Tidal data for a new port is entered as follows:
1.
Enter Plan Voyage mode by pressing the MODE key followed by function
key Plan Voyage.

The following data can be input for each port:
ID
Port No. from ATT part III.
Name
Place name from ATT part III.
Zone
UTC offset time zone (UTC time – Local Time) in hours and
minutes from ATT part III. This information is important since
ATT data is referenced to a local time in port with this offset
from UTC. Enter this data as defined in ATT regardless of
adjustments for other local time offsets (e.g daylight savings
time). See further notes on treatment of time offset in sections
below.
Position
Latitude & longitude of port. This is optional information that is not
required for calculation of tide. If entered, the current distance
to the actual port will be shown in the list of tidal stations.
Position is not listed in ATT part III.
ML (Z0)
This is mean level in meters from ATT part III. For most stations
this is a fixed value. Tables of seasonal corrections and
fortnightly variations as required for some stations can be
entered as described below.
ML Seasonal
Seasonal corrections to the mean level value as defined for
some ports. If so, this parameter shall be set to ‗Use Table‘
which will provide a new function key Edit Table. Use this key to
access an editable list of values for each month and input the
corrections listed in ATT part III.
ML Fortnightly
Fortnightly variations in mean level as defined for some ports. If
so, this parameter shall be set to ‗Use Table‘ which will provide
a new function key Edit Table. Use this key to access an
editable list of parameters to be entered from a supplementary
table in ATT. When used, a lock icon will be displayed next to
the ML(Z0) parameter in the list and the ML(Z0) value will be
replaced by a ‗W‘. This indicates that the actual value used will
be deduced from the fortnightly parameters.
M2(G)
Harmonic constant from ATT part III.
M2(H.m)
Harmonic constant from ATT part III. Fixed value used for most
ports.
M2 Seasonal
Seasonal depending values of M2(H.m) as defined for some
ports. If so, this parameter shall be set to ‗Use Table‘ which will
provide a new function key Edit Table. Use this key to access
an editable list of values for each month and input values listed
in ATT part III. When used, a lock icon will be displayed next to
the M2(H.m) parameter in the list and the M2(H.m) value will be
replaced by a ‗v‘. This indicates that the actual value used will

4.9.6.5
Treatment of Local Time Frames
For each port, a ‗Zone‘ parameter shall be entered as defined in ATT part III. This
parameter defines the relationship of data published in ATT with respect to UTC.
When a tide prediction is generated, a graph will be displayed for 00 to 24 hours of a
selected date. This time will be in UTC or with any user selectable local time offset
as defined in the Time Configuration view. If UTC is used, times will be denoted
‗UTC‘. If a local time frame is used, times will be denoted ‗LOC‘. This is in analogy
with how all times generally are treated by the display.
Thus, it is important to realize that a tide displayed in ‗LOC‘ time not necessary is
the local time in port defined by the ‗Zone‘ parameter. If this is desired, the user
must manually define a local time in the Time Configuration view that corresponds to
the ‗Zone‘ value for the actual port.
To make things more complicated, the ‗Zone‘ parameter in ATT part III is defined as
(UTC time – Local Time) and thus being negative when moving eastwards from
Greenwich. On the other hand, the local time offset in the Time Configuration view is
to be added to UTC and thus positive when moving eastwards. Thus, a negative
‗Zone‘ value is equivalent to a positive offset of time configuration and vice versa.
Thus, in general: always enter ‗Zone‘ for the port as indicated in ATT part III and
select local time offset in Time Configuration view to obtain the desired local time
frame for which the prediction is to be obtained.
Examples of ‗Zone‘ setting and corresponding local time configuration are shown in
the following two figures.

a waypoint is considered passed. The parameter can be set to one of Manual,
Distance, Bisector Line or Perpendicular Line. The different waypoint pass criteria are
described in chapter 2 on page 11.
WPT Pass Distance
The Waypoint Pass Distance parameter specifies the distance to the waypoint where it
is considered passed when using the Distance waypoint pass criteria.
Start Sail From
It is possible to select whether an initial ‗from‘ waypoint shall be inserted when starting
an active route.
When this function is activated, the current position will be grabbed and stored in the
active route as an initial ‗from‘ waypoint with identifier ‗t1‘. This waypoint will not be
added to the waypoint database (functionality in line with XTE reset waypoints).
If ‗t1‘ subsequently is manually selected as the next waypoint in the route, function will
be identical as the prior implementation when navigating towards first waypoint (no
XTE computed and current position output as ‗from‘ waypoint with identifier ‗t0‘ in active
route RTE message).
It is now possible to insert a waypoint at current position using the ‗reset XTE‘ function
also while navigating towards the first waypoint in a route.

Default RAIM
This field sets the default RAIM accuracy level to appear when specifying a RAIM
accuracy level for a leg in a route. See section 0 ―RAIM Accuracy Level‖ on page 11 for
more information.
Navigation Algorithm
The Navigation Algorithm parameter specifies the default navigation algorithm for
newly created legs. The algorithm can either be set to Rhumb Line or Great Circle. The
difference between these algorithms are described in chapter 2 on page 11. This
parameter also determines the navigation algorithm used when sailing towards the first
waypoint in a route or towards a single waypoint.
XTE Limit
The Cross-Track Limit parameter specifies the cross-track error limit used when
navigating. If the cross-track error becomes larger than the set XTE Limit, the XTE
Limit Exceeded alarm is raised and remains active until the cross-track error becomes
less than the set XTE Limit, or navigation along the active route stops.
Approach Distance
The Approach Distance parameter specifies the distance from next waypoint where the
Waypoint Approaching (Distance) alarm is raised.
Approach Time
The Approach Time parameter specifies the estimated time (in minutes) before arrival
to the next waypoint when the Waypoint Approaching (Time) alarm is raised.
RTE Nav Algorithm
The RTE Navigation Algorithm specifies the navigation algorithm that is set for routes
received from external systems, for example from ECDIS systems. See section 5.2.1
―Download Waypoints and Routes‖ on page 160 in the Appendix chapter for more
information.
RTE/Rnn WP Limit
With Navigation Display software 5.0.96 and onwards, it is now possible to
configure the maximum number of remaining waypoints in the active route that shall be
transmitted in RTE and Rnn messages. Previously, only the four next waypoints were
transmitted per default. This value can now be configured between 4 and 13 with the
RTE/Rnn WP Limit parameter. The default value is 4.

Average ETA SOG
The Average ETA SOG parameter defines the time period over which average speed is
calculated when estimating time of arrival (ETA) to the end of the active route and Time
To Go (TTG) to the next waypoint.
Status Information
The Status Information parameter defines whether current position (when available)
from the navigation sensor or the name of the next waypoint is to be displayed in
the status bar at the upper left corner of the display.
-Local Time Zone Offset- Output in ZDA
The Output in ZDA parameter defines if the local time zone offset set in the Time
Config dialog (see section 4.11.2) should be output in ZDA messages. When the
parameter is set to Disabled the local time zone offset fields in ZDA messages will be
null fields. When set to Enabled the local time zone offset fields in ZDA messages will
be defined by the settings in Time Config dialog. If UTC time is used the fields will be
zeros in ZDA messages.

Alarm Config
The Alarm Configuration view is used to configure the action the system should
perform when a specific alarm is raised. The possible settings for each alarm are:
Disabled. The alarm will not be indicated when active.
Popup. An alarm pop-up will be displayed when the alarm becomes active.
See section 3.2.3 ―Alarm Pop-Ups‖ on page 16.
External. The Alarm Output signal will be activated when the alarm is
active, typically triggering a visual alarm indicator and/or alarm bell. This
setting will also generate alarm messages on the serial interface provided
that the NMEA ALR message has been enabled on the specific port.
Popup & External. The alarm will result in both an alarm pop-up dialog and
external alarm signal being activated.
It is possible to disable alarms that are of no interest for the operator by setting them to
Disabled.
In this view it is also possible to enable and disable the use of an external alarm
acknowledge momentary switch for acknowledging alarms. This is controlled by the
Allow External Ack parameter. An external acknowledge input signal will acknowledge
all active alarms.
With Navigation Display software 5.0.96 and onwards, it is now possible to
configure whether the external alarm discrete output will be reset as soon as all active
alarms (of alarm types configured as ‗external‘) have been acknowledged or will remain
set as long as any (‗external‘) active alarm condition is present. This is determined by
the ‗Ack Disables Ext ALR‘ parameter in the Alarm Configuration view in Configuration
mode as illustrated below. The default setting of ‗Ack Disables Ext ALR‘ is ‗Yes‘. This
corresponds to the behavior of the discrete alarm output in previous versions of the
Navigation system before this setting was available.
Specific external navigation alarms may be acknowledged through the serial interface
using the NMEA ‗ACK‘ sentence.

Range Unit
The unit used when displaying range values. Can be set to one of Nautical Mile, Kilometers and Statute Mile. The Navigation Display Software 5.0.96 and onwards has
an improved range resolution. A range value (in NM, Km or Statute miles) not
exceeding 1.0 in the given unit will now be displayed without the leading zero. Range
resolution at short range is thus increased to three decimals.

GPS/DGPS Config
The view contains the GPS Configuration and SBAS Configuration subviews. When an
DGPS Navigation Sensor is used, the view will also include the Beacon
Configuration and Beacon Database subviews. The views are used to configure GPS,
SBAS and Beacon settings of the Navigation Sensor.
4.11.7.1
GPS Config
The GPS Configuration view allows the user to configure current GPS settings of the
Navigation Sensor. The following fields can be changed.
Elevation Mask
This parameter sets the elevation cutoff mask angle, in degrees, for the GPS. Any
satellites below this mask angle will be ignored, even if available. The value should
be between 0 and 60 degrees, and the default value is 5 degrees.
Correction Age
This field sets the maximum allowed age (in seconds) for correction data. The
Navigation Sensor is able to use old correction data for extended periods of time.
The default setting is 120 seconds. The lowest allowed value is 10 seconds and the
highest 900 seconds. When increasing the allowed correction age, ensure that the
new setting meets your requirements as accuracy will degrade with increasing
correction age.
Correction Source
This parameter sets the source for differential corrections. Valid settings are:
Beacon. In this setting the system will use signals from IALA radio
beacon stations as source for differential corrections. This setting is only
available when using a DGPS Navigation Sensor (the DGPS
configuration).
SBAS. This setting makes the system use SBAS satellite signals as
source for differential corrections.
User Port 1. This setting will command the system to apply external
differential corrections received in RTCM SC-104 format on the User 1
port. The User 1 port will not be available for output of serial data from
the system if this setting is selected.
None. This setting makes the system operate in autonomous mode, not
using any differential corrections.
ATTENTION: Both the EGNOS and MSAS satellite based augmentation systems
(SBAS) are currently under development. Signals from these systems are therefore
used entirely at your own risk.

SOG Smoothing Parameter
The SOG Smoothing parameter allows you to adjust the level of responsiveness of
the speed over ground (SOG) measurement, as displayed by the Display and
provided in the $GPVTG and $GPRMC sentences. The default value is zero, and
increasing the value will increase the level of SOG smoothing.
The setting of this parameter depends upon the expected dynamics of the vessel. If
a ship is highly dynamic, this value should be set to a lower value since the filtering
window needs be shorter in time, resulting in a more responsive measurement.
However, if a vessel is very large and has much more resistance to change in its
motion, this value can be increased to reduce measurement noise. The following
formula provides some guidance on how to set this value. If unsure on which
value to set, it's best to be conservative and leave this parameter at the default
setting of 0.0 seconds.
SOG smoothing = 10 / maximum acceleration (in m/s²).
COG Smoothing Parameter
The COG Smoothing parameter allows you to adjust the level of responsiveness of
the course over ground (COG) measurement, as displayed by the Display and
provided in the $GPVTG and $GPRMC sentences. The default value is zero, and
increasing the value will increase the level of COG smoothing.
As with the SOG smoothing parameter, the setting of this parameter depends upon
the expected dynamics of the vessel. If a ship is highly dynamic, this value should
be set to a lower value since the filtering window needs be shorter in time, resulting
in a more responsive measurement. However, if a vessel is very large and has
much more resistance to change in its motion, this value can be increased to reduce
measurement noise. The following formula provides some guidance on how to set
this value initially. It is however recommended that you test how the revised value
works in practice. If unsure on which value to set, it's best to be conservative
and leave this parameter at the default setting of 0.0 seconds.
COG smoothing = 10 / maximum rate of change in course (in °/s).
Note: The ship needs to be moving to calculate a valid COG value. Do not use COG
values output while the ship is at rest as a basis for adjusting this parameter.
The GPS Configuration view is illustrated below.

Beacon Config
The Beacon Configuration view is used to configure beacon receiver parameters of
the DGPS Navigation Sensor. This includes setting the frequency and bit rate
mode, as well as the radio beacon frequency and bit rate if manual mode is used.
Note: The Beacon Configuration view is only present when using a DGPS
Navigation Sensor.
Tuning Mode
The Tuning Mode parameter sets the frequency selection mode of the DGPS
Navigation Sensor internal radio beacon receiver. The mode can be Frequency
Scan, Manual or Database (Auto). The Database mode is only available when then
the Beacon Database is enabled. In Frequency Scan mode, the beacon receiver will
search available frequencies and tune to the strongest beacon signal. In this mode,
the Navigation Sensor continuously performs background search to discover
higher quality DGPS signals. While performing background searches, the
Navigation Sensor continues to receive differential corrections from the current radio
beacon station.
In Manual tuning mode, the DGPS Navigation Sensor tunes to the specified
beacon frequency for receiving DGPS signals.
In Database mode, the receiver will search for the closest station based on its
current location and distance to the internal list of station locations. The frequency
and bit rate specified in the station database will be used and therefore these
parameters are locked when the Tuning Mode parameter is set to Database (Auto).
Frequency
The Frequency parameter is used to set the frequency to use for receiving DGPS
signals, when the frequency mode parameter is set to manual. Valid frequencies are
between 283.5 and 325 KHz, at 0.5 kHz intervals. This parameter is locked when
Tuning Mode is set to Frequency Scan or Database (Auto).
Bit Rate Mode
The Bit Rate Mode parameter sets the bit rate mode, to either Automatic or Manual.
In Automatic mode the DGPS Navigation Sensor will automatically select the
correct bit rate to use for demodulating the radio beacon signal. In Manual mode,
the DGPS Navigation Sensor will use the specified bit rate.
This parameter is locked to Auto when Tuning Mode is set to Database (Auto)
since the bit rate specified in the database will be automatically used.
Bit Rate
The Bit Rate parameter is used to set the bit rate used for demodulation of the
DGPS signal, when using the manual bit rate mode. The bit rate can be set to one of
50, 100 and 200 bps. This parameter is locked when Bit Rate Mode is set to Auto.

Redundant Mode
In a redundant system configuration two interconnected navigation systems
automatically synchronize their internal data bases and some settings.
The systems to be synchronized are to be interconnected by their User 3 serial
ports‗ AUX‘ ports (or by the ‗AUX‘ port of the combined system and the User 3 port
of an Navigation system) . These ports are thus not available for other purposes
in this configuration.
During synchronized operation, any changes to a synchronized item performed by
the user at one system will also be incorporated in the other system. This applies
regardless if the change is made through a manual input or by the serial interface.
It is the responsibility of the user not to input conflicting information to the two
systems, such as different waypoints with identical names. The general rule is that
the last change will override any previous inputs in such a case.
The following items are synchronized:
Waypoints.
Routes.
Active Route.
XTE reset function.
MOB function.
RAIM setting.
Target ETA.
Waypoint pass criterion (Nav Config).
Waypoint pass distance (Nav Config).
Default RAIM value (Nav Config).
Nav Algorithm (Nav Config).
XTE limit (Nav Config).
Approach distance (Nav Config).
Default nav algorithm for received routes (Nav Config).
Averaging time for SOG used in ETA and TTG calculations (Nav Config).
When the Mode parameter is set to anything but Stand-Alone, communication with
an external unit is to be expected. Current status of redundant operation is indicated
by icons in the status bar at the top of the display as follows:
Redundant operation active.

Note 1: At the initial synchronization, all contents in both systems will be set equal to
the contents of the system that synchronization is made from. Unique contents of
the other (receiving) system will be erased.
Note 2: During the initial synchronization process, the receiving unit (as indicated by
the
icon) will have a large numbers of its functions temporarily disabled. For
instance, any active route or active MOB function will be terminated and any
attempts to modify the route/waypoint database (either by manual inputs or by the
serial interface) will be rejected.

Output Config
The Port Output Configuration view is used to configure which sentences are output
on the User Ports of the Navigation System, and how often they are sent. In the
Output Configuration subview for each user port, current load on the port is
displayed. This gives an indication on how much of the port‘s baud rate that is used
up by the enabled sentences. Only turn on the sentences that you intend to use.
If no response is received from the Navigation Sensor, the Navigation Sensor
dependant sentences will be locked.
For a list of output sentences available on the different serial ports, refer to the
Navigation System installation manual (P/N SAA7000 109-142).

RTCM output on User 2 Port
It is possible to output correction data from the internal DGPS beacon receiver in
RTCM format on the user 2 port. This function is available only if the Navigation
Display is used together with an DGPS Navigation Sensor with routing software
version 1.07 or higher.
To determine current system type and current version of routing software proceed
as described in section 4.11.11.
If this function is available, an ‗RTCM‘ option will be added to the list of output
messages in the User 2 Port Output Configuration view as illustrated below.
Figure 153 - User Port 2 Output Configuration
It is possible to interleave RTCM output data with the ordinary NMEA style text
messages on the User 2 port. However, this may be a problem for receiving
equipment and thus it is recommended that all other User 2 Port output messages
shall be set to ‗Disabled‘ when this feature is used.
The baud rate for RTCM output data is controlled by the ‗User Port 2‘ rate parameter
in the Port Rate Configuration view. Selectable rates are 4800, 9600 and 19200.
4.11.10 Port Rate Config
The Port Rate Configuration view allows the user to configure the communication rate
used for the serial ports in the Navigation System, and the output rate of the Speed
Log Output binary port. The view also makes it possible to view the data that is
received on the different serial ports.
The rate for the Speed Log Output binary port can be set to one of Disabled, 100, 200,
300 or 400 pulses per nautical mile (P/Nm). The default setting is that Speed Log
output is disabled. The output pulse period has a resolution of 50 ms providing a
resolution of 0.5 knots up to 10-20 knots depending on pulse rate with a working range
up to 30 knots.

Transfer Waypoint and Routes
The Navigation System supports both download and upload of waypoints and routes
from/to ECDIS and other external systems. The system also supports continuous output
of the current active route. Waypoints and routes are transferred using the WPL and RTE
sentences. The WPL and RTE sentences are interpreted according to the IEC 61162-1
(2000) standard. The Rnn sentence is supported but for NMEA backward compliance
only. It can only be used to output and receive active routes.
5.2.1
Download Waypoints and Routes
Waypoints and complete routes can be received on both user port 1 and 3, using the
WPL and RTE sentences. Active route can also be received using the Rnn sentence.
Which sentences that should be interpreted can be configured in the Wp/Rte Input
view, described on page 147.
Received routes are assigned the navigation algorithm specified by the parameter RTE
Nav Algorithm, described in section 4.11.4 ―Nav Config‖ on page 125. The
Navigation System can store a maximum of 2000 waypoints and 100 routes.
5.2.1.1
Waypoint and Complete Route Downloads
Received waypoints and complete routes will be stored in the Display, and will
automatically replace any existing waypoints/routes with the same name.
5.2.1.2
Working Route Downloads
A working route indicated by the Message mode field being set to ‗w‘ in the RTE
sentence that is received by the Navigation System will automatically become
the new active route of the system, and replace any existing active route.
Routes received using the Rnn sentence will also automatically become the new
active route. The ‗nn‘ part of the Rnn sentence is interpreted in the same way as the
Route identifier field of the RTE sentence, i.e. as route name.
The first received waypoint of a working route will become the first ‗from‘ waypoint
and the second waypoint received will become the first ‗to‘ waypoint of the active
route. This is in accordance with the interpretation of the RTE sentence for working
routes as defined in IEC standard 61162-1.
5.2.2
Upload Waypoints and Complete Routes
Uploaded waypoints and routes will be output using the WPL and RTE sentences, on
the serial port where the sentence WPL/RTE Upload is enabled. See section ―Output
Config‖ on page 148 for details on enabling output sentences.
To upload a waypoint, go to the Waypoint List view described on page 98 and use the
Upload Waypoint function key to transmit information about the highlighted waypoint on
the configured serial port(s). It is also possible to upload the complete set of waypoints
with a function key labelled Upload All Wps. To upload a complete route, go to the
Route List view described on page 81 and use the Upload Route function key to
transmit information about the highlighted route and all associated waypoints.
Operator Manual
APPENDIX
SAA7000 109-143, H
Page 160
5.2.3
Output Working Route and Remaining Waypoints
The system supports output of the current active route (the working route) and the
remaining waypoints of the route. The active route can be transmitted both using
WPL/RTE and WPL/RNN sentences. Usage of WPL/RTE is recommended.
When navigating towards the first waypoint of the route, the ship‘s current position is
output as the origin waypoint. This waypoint is named ―t0‖ when using WPL/RTE and
―0000‖ when using WPL/RNN.
When transmitting active route data using WPL/RNN, the waypoints in the active route
are given a number corresponding to their position in the route, starting from ―0001‖.
The ―NN‖ field in RNN is always ―00‖.
The number of remaining waypoints of the active route that are outputted is determined
by the RTE/Rnn WP Limit parameter described in section 4.11.4.
Enabling output sentences is described in section 4.11.9.5 ―Output Config‖ on page
148.
