About navigating

The navigation function included in the system allows you to navigate to the cursor position,
to a waypoint, or along a predefined route.

If autopilot functionality is included in your system, the autopilot can be set to automatically
navigate the vessel.

For information about positioning waypoints and creating routes, refer to "Waypoints, routes, and
tracks" on page 36.

Navigate to cursor position

You can start navigating to a cursor position on any chart, radar, or echosounder panel.
Position the cursor at the selected destination on the panel, and then select the go to cursor

menu option.

Note: The go to cursor menu option is not available if you are already navigating.

Ú

Navigating to a waypoint

You can navigate to a waypoint:

• from a chart

• using the waypoint dialog

When navigating to a waypoint, the menu expands and shows options for canceling and for
restarting the navigation from current vessel position.

Navigating a route

You can start navigating a route from:

• the chart panel

44

Navigating | Zeus³S Operation Manual

• the route dialog

When route navigation is viewed, the menu expands and shows options for canceling the
navigation, for skipping a waypoint, and for restarting the route from current vessel position.

Starting a route from the chart panel

Activate a route on the panel, and then select the route navigation option from the menu.
You can select a routepoint to start navigating from a selected position.

Navigating with the autopilot

When you start navigation on a system with autopilot functionality, you are prompted to set
the autopilot to navigation mode.

Note: The prompt to set the autopilot to navigation mode is disabled if the boat type is

Ú

set to SAIL in the Autopilot Commissioning dialog.

If you choose not to engage the autopilot, the autopilot can be set to navigation mode from
the Autopilot Controller later on.

For more information about autopilot functionality, refer to the autopilot chapter of the
autopilot being used.

Navigation settings

Navigation method

Different methods are available for calculating the distance and bearing between any two
geographical points.

Navigating | Zeus³S Operation Manual

45

The Great circle route is the shortest path between two points. However, if you are to travel
along such a route, it would be difficult to steer manually as the heading would constantly
be changing (except in the case of due north, south, or along the equator).

Rhumb lines are tracks of constant bearing. It is possible to travel between two locations
using Rhumb line computation, but the distance would usually be greater than if Great circle
is used.

Arrival radius

Sets an invisible circle around the destination waypoint. The vessel is considered arrived at
the waypoint when it is within this radius.

When you are navigating a route, the arrival radius defines the point at which a turn is
initiated.

The arrival circle (1) should be adjusted according to boat speed. The higher the speed, the
wider the circle.

The intention is to make the autopilot start the heading change in due time to make a
smooth turn onto the next leg.

The figure below may be used to select the appropriate waypoint circle when creating the
route.

46

Note: The distance between any waypoints in a route must not be smaller than the

Ú

radius of the waypoint arrival circle.

XTE limit

Defines how far the vessel can deviate from the selected route. If the vessel goes beyond this
limit, an alarm is activated.

Arrival alarm

When the arrival alarm is enabled, an alarm is activated when the vessel reaches the
waypoint or when it is within the specified arrival radius.

Magnetic variation

Magnetic variation is the difference between true bearings and magnetic bearings, caused
by different locations of the Geographic and the Magnetic north poles. Any local anomalies
such as iron deposits might also affect the magnetic bearings.

When set to Auto, the system automatically converts magnetic north to true north. Select
manual mode if you need to enter your own local magnetic variation.

• DIST S - Distance to starboard end of start line

• BIAS - Start line bias angle

• RACE TIMER - Time on the race timer

• BIAS ADV - Bias advantage (meters or boat lengths)

Setting up a start line

The start line is a visual aid that shows the distance from the boat to the start line, tide
direction, recommended start end bias, and what advantage in degrees and distance the
biased end will give. The start line is a line between the port and starboard end points.

Note: If you have an H5000 CPU on your network, the start line information between the

Ú

MFD and the H5000 is shared. The start line data numbers are calculated on the H5000
CPU and sent across the network. There is only one start line. If you set the start line on
the MFD, it will show on the H5000 Graphic Display and vice-versa.

Note: Before setting the start line position it is important that the GPS Bow offset is

Ú

updated to negate the difference between the GPS position and the bow of the vessel.
This setting is made in the Advanced settings dialog under Instruments. Your Boat
settings must also be entered in the Boat settings dialog which is available from the
Chart settings dialog.

Menu options let you use different methods for setting the port and starboard start line ends.
You can ping them, set them at cursor position, specify coordinates, and set one based on the
setting of the other. You can also edit waypoints to create start line end points. After the
ends are set you can nudge each end to move them, if needed.

The menu options to set the port and starboard start line end points are available in both the
Chart panel and the Race panel.

Setting start line end points by pinging

Setting the start line end points by pinging requires maneuvering the boat to each end of
the start line and then pinging.

Note: Before setting the start line position using the ping method, it is important that

Ú

the Bow offset is updated to negate the difference between the GPS position and the
bow of the vessel.

Safe operation with the autopilot

Warning: An autopilot is a useful navigational aid, but DOES NOT replace

a human navigator.

Warning: Ensure the autopilot has been installed correctly, commissioned

and calibrated before use.

Note: For safety reasons a physical standby key should be available.

Ú

Note: The WheelKey can be configured to be a standby key. Refer to "Configurable WheelKey"

Ú

on page 18.

Do not use automatic steering when:

• In heavy traffic areas or in narrow waters

• In poor visibility or extreme sea conditions

• When in areas where use of an autopilot is prohibited by law

When using an autopilot:

• Do not leave the helm unattended

• Do not place any magnetic material or equipment near the heading sensor used by the

autopilot system

• Verify at regular intervals the course and position of the vessel

• Always switch the autopilot to standby and reduce speed in due time to avoid hazardous

situations

Autopilot alarms

For safety reasons it is recommended to turn on all autopilot alarms when operating the
autopilot.

For more information, refer to "Alarms" on page 126.

Selecting active autopilot

If 2 autopilot computers are configured for MFD control, only one of them can be active at a
time. We recommend you only power up one at a time.

The Autopilot controller

The Autopilot controller has a fixed position on the left-side of the page.
The following Autopilot controller options are available:

• Autopilot controller, showing active mode, heading, rudder and various steering

information depending on active autopilot mode. Manual adjustments to the set
heading/course can only be made when the port and starboard arrow indicators are
illuminated red and green.

Autopilot modes

The autopilot has several steering modes. The number of modes and features within the
mode depend on the autopilot computer, the boat type and available inputs.

Non-Follow Up mode (NFU)

In this mode the port and starboard buttons are used to control the rudder.
Activate this mode by selecting the port or starboard button when the autopilot is in

standby.

Autopilot| Zeus³S Operation Manual

Follow-Up mode (FU)

W

W

In this mode the rudder moves to a set rudder angle. The rudder position is maintained at
the set angle.

To change the set rudder angle

• Select the port or starboard button

• With the autopilot controller active, turn the rotary knob

Heading hold mode (A)

In this mode the autopilot steers the vessel on the set heading.
When the mode is activated, the autopilot selects the current compass heading as the set

heading.

Note: In this mode the autopilot does not compensate for any drifting caused by current

Ú

and/or wind (W).

To change the set heading

• Select a port or starboard button

• With the autopilot controller active, turn the rotary knob

An immediate heading change takes place. The heading is maintained until a new heading is
set.

Tacking in Heading hold mode

Note: Only available when the boat type is set to sail (autopilot configuration).

Ú

Note: Tacking should only be performed into the wind and must be tried out in calm sea

Ú

conditions with light wind to find out how it works on your vessel.

Tacking in heading hold mode changes the heading by a fixed tack angle, either to port or
starboard.

The rate of turn during the tack/gybe is set by the tack time in the autopilot settings dialog.
Refer to "Autopilot settings" on page 71.

To initiate a tack:

• Selecting the tack button in the mode list, then selecting the tack direction.

NoDrift mode

In NoDrift mode the vessel is steered along a calculated track line, from present position and
in a direction set by the user.

When the mode is activated, the autopilot will draw an invisible track line based on current
heading from the vessel’s position. The autopilot will now use the position information to
calculate the cross track distance, and automatically steer along the calculated track.

Note: If the vessel is drifting away from the track line due to current and/or wind (W), the

Ú

vessel will follow the line with a crab angle.

To change the set track line

• Select a port or starboard button

• With the autopilot controller active, turn the rotary knob

NAV mode

Warning: NAV mode should only be used in open waters. Navigation

mode must not be used while sailing, as course changes may result in
unexpected tacks or gybes.

Prior to entering NAV mode you must be navigating a route or towards a waypoint.

Autopilot| Zeus³S Operation Manual

69

In NAV mode the autopilot automatically steers the vessel to a specific waypoint location, or
along a pre-defined route. Position information is used to change the course to steer to keep
the vessel on the track line to the destination waypoint.

Note: For information about navigation, refer to "Navigating" on page 44.

Ú

NAV mode options

While in NAV mode the following buttons are available in the autopilot controller:

Restart

Restarts the navigation from the vessel’s current position.

Skip

Skips the active waypoint and steers towards the next waypoint. This option is only available
when navigating a route with more than one waypoint between the vessel position and the
end of the route.

Cancel

Cancels active navigation and deselects the current route or waypoint navigation. The
autopilot is switched to heading hold mode, steering the vessel on the heading that was
active when the cancel button was selected.

Note: This is different from selecting standby which does not stop current navigation.

Ú

Turning in NAV mode

When the vessel reaches a waypoint, the autopilot will give an audible warning and display a
dialog with the new course information.

There is a limit for the allowed automatic course change to next waypoint in a route:

• If the required course change to the next waypoint is less than the course change limit,

the autopilot will automatically change the course

• If the required course change to next waypoint is more than the set limit, you are

prompted to verify that the upcoming course change is acceptable. If the turn is not
accepted, the vessel will continue with the current set heading.

The course change limit setting depends on the autopilot computer. Refer to the autopilot
computer documentation.

Wind mode

Note: Wind mode is only available when the boat type is set to Sail. It is not possible to

Ú

activate wind mode if wind information is missing.

In wind mode the autopilot captures the current wind angle as steering reference, and
adjusts the heading of the boat to maintain this wind angle.

The autopilot will keep the boat on the set wind angle until a new wind angle is set.

Warning: In wind mode the autopilot steers to the apparent or true wind

angle and not to a compass heading. Any wind shift could result in the
vessel steering on an undesired course.

70

To change the set wind reference angle

• Select a port or starboard button

• With the autopilot controller active, turn the rotary knob

An immediate change of wind reference angle takes place.

Tacking and gybing in wind mode

The tack/gybe option in wind mode mirrors the set wind angle on the opposite tack.

Autopilot| Zeus³S Operation Manual

Tacking and gybing in wind mode can be performed when sailing with apparent or true
wind as the reference. In either case the true wind angle must be less than 90° (tacking) and
more than 120° (gybing).

The rate of turn during the tack/gybe is set by the tack time in the autopilot settings dialog.
Refer to "Autopilot settings" on page 71.

To initiate a tack or gybe:

• Select the Tack/Gybe option in the mode list

Note: The autopilot will temporarily add a 5° bear-away on the new tack to allow the

Ú

boat to pick up speed. After a short period the wind angle will return to the set angle.

Autopilot settings

The Autopilot settings dialog depends on which autopilot computer that is connected to the
system. If more than one autopilot is connected, the Autopilot settings dialog shows option
for the active autopilot.

The autopilot settings can be split between settings done by the user, and settings done
during installation and commissioning of the autopilot system.

User settings can be changed for various operational conditions or user preferences.

•

• Installation settings are defined during commissioning of the autopilot system. No

changes should later be done to these settings.

The following sections describe the user settings per autopilot computer. For installation
settings, refer to the installation manual.

Common user settings

The following user settings are common to all autopilots.

Selecting the low speed option or the high speed option opens dialogs the following
parameters can be changed.

• Turn rate: Preferred turn rate used while turning in degrees per minute.

• Rudder gain: This parameter determines the ratio between commanded rudder and the

heading error. The higher rudder value the more rudder is applied. If the value is too small
it will take a long time to compensate for a heading error, and the autopilot will fail to
keep a steady course. If the value is set too high the overshoot will increase and the
steering will be unstable.

• Counter rudder: Relation between change in heading error and applied rudder. Higher

counter rudder will reduce applied rudder faster when approaching the set heading.

• Auto trim: Controls how aggressively the autopilot will apply rudder to compensate for a

constant heading offset, e.g. when external forces such as wind or current affects the
heading. Lower auto trim will give faster, limitation of a constant heading offset.

• Init rudder: Defines how the system moves the rudder when switching from manual

steering to an automatic mode.

About radar

Several radar sensors are supported.
This chapter describes features and options for a variety of supported radars. The features

and options available to you are dependent on the radar antenna(s) connected to your
system.

The Radar panel

A Radar information window
B Heading line*
C Compass*
D Range rings *

E Quick image controls
F Data bar**

* Optional radar symbology. Radar symbology can be turned ON/OFF collectively from the
radar menu, or individually as described in radar settings dialog.

** You can show or hide the data bar using the data bar option in the radar settings dialog.

Dual radar

You can connect to any combination of two supported radars and see both radar images at
the same time.

Note: Interference will be seen on the Broadband Radar on most ranges when a pulse or

Ú

Halo radar, and a Broadband radar are transmitting at the same time on the same boat.
We recommend to only transmit on one radar at a time. For example, transmit
Broadband radar for typical navigational usage, or pulse or Halo radar to locate weather
cells, defined coastlines at a distance and to trigger Racons.

You can select a dual radar panel by pressing and holding the Radar application button on
the home page, or by creating a favorite page with two radar panels.

Selecting the radar source

You specify the radar in the Radar panel by selecting one of the available radars in the radar
source menu option. If you have a multiple Radar panel, the radar is set individually for each
radar panel. Activate one of the radar panels, and then select one of the available radars in
the radar source menu option. Repeat the process for the second radar panel, and select an
alternative radar for this panel.

Note: The 3-digit radar source number is the last 3 digits of the radar's serial number.

Ú

Radar| Zeus³S Operation Manual

75

Radar overlay

You can overlay the Radar image on the Chart. This can help you to easily interpret the radar
image by correlating the radar targets with charted objects.

Note: A heading sensor must be present in the system for radar overlay.

Ú

When the radar overlay is selected, basic radar operational functions are available from the
Chart panel’s menu.

Selecting radar overlay source on chart panels

To select the radar source of the radar overlay displayed on the chart panel, use the Radar
options and then Source chart panel menu options to select the radar source.

For chart pages with more than one chart with radar overlay, it is possible to set up different
radars sources for each chart panel. Activate one of the chart panels and then select one of
the available radars in the radar source menu option. Repeat the process for the second chart
panel with radar overlay, and select an alternative radar for this panel.

Radar operational modes

The radar’s operational modes are controlled from the Radar menu. The following modes are
available:

Power off

The power to the radar scanner is turned off. Power off is only available when radar is in
standby mode.

Standby

The power to the radar scanner is on, but the radar is not transmitting.

Note: You can also put the radar in standby mode from the System Controls dialog.

Ú

Transmit

The scanner is on and transmitting. Detected targets are drawn on the radar PPI (Plan
Position Indicator).

Note: You can also put the radar in transmit mode from the System Controls dialog.

Ú

Radar Range

You adjust radar range by selecting the zoom icons on the radar panel.

Dual range

When connected to a radar with dual range capability, it is possible to run the radar in Dual
Range mode.

The radar appears in the radar sources menu as two virtual radar sources A and B. Range and
radar controls for each virtual radar source are fully independent and the source can be
selected for a particular chart or radar panel in the same manner as dual radar described in
"Selecting the radar source" on page 75.

Note: Some controls that are related to physical properties of the radar itself are not

Ú

independent of source. These are Fast Scan, Antenna Height and Bearing alignment.

76

MARPA is fully independent and up to 10 targets may be tracked for each virtual radar
source.

Up to two independent Guard Zones may also be defined for each virtual radar source.

Radar sector blanking

If your radar has sector blanking capability, you can define up to four sectors on the PPI inside
which no radar data is transmitted. This enables you to blank-out interference caused by
features on your boat or from a secondary radar. The blanking occurs on the main radar

Radar| Zeus³S Operation Manual

image and radar overlay on a chart. An enabled sector is shown as a magenta outline with 3
arcs crossing the blanking area. To specify radar sector blanking, refer to the unit's installation
manual.

Main radar PPI Radar overlay on a chart

Adjusting the radar image

You may be able to improve the radar image by adjusting the radar sensitivity, and by
filtering out the random echoes from sea and weather conditions.

The radar control images are located in the upper right corner of the radar panel. You can
adjust the image settings by selecting the radar control image or by pressing the rotary knob.
The selected control expands and displays its name in full and a slide bar is displayed. You
can then adjust the value by turning the rotary know or by using the slide bar.

You can also adjust the image settings from the radar menu.
Menu options can vary depending on your radar's capability.

Radar modes

Use modes are available with preset control settings for different environments. Not all
modes are available for all radar transceivers.

Modes in dual ranges

When connected to a radar with dual range capability, it is possible to run the radar in Dual
Range mode.

Modes can be set independently for each range. For example, you can have Offshore mode
for range A and Weather mode for range B. However, interaction between ranges occurs in
some cases:

• When using Bird mode for both ranges, maximum range is restricted to 24 NM and range

resolution is reduced.

• Fast scan - The antenna rotation speed is set to the slower of the two modes selected. For

example, Fast Scan is disabled when using Harbor and Weather modes because Fast Scan
is Off in Weather mode.

• The Interference reject setting can affect the interference seen or removed on both

ranges.

Directional clutter rejection

This mode automatically works when GAIN = AUTO and SEA = HARBOR or OFFSHORE. The
purpose is to allow smaller vessels to be seen in the leeward direction of the sea clutter. The
GAIN of the radar receiver is increased dynamically during the sweep, in the leeward
direction, for increased target sensitivity in heavier sea states.

When GAIN or SEA = MANUAL, the Directional Clutter Rejection mode will be OFF (non­directional).

In addition, CALM, MODERATE or ROUGH STC Curve settings are available in the Radar
options menu to better optimize the radar image to your liking.

Gain

The gain controls the sensitivity of the radar receiver.
A higher gain makes the radar more sensitive to radar returns, allowing it to display weaker

targets. If the gain is set too high, the image might be cluttered with background noise.

Radar| Zeus³S Operation Manual

77

Gain has a manual and an automatic mode. You toggle between automatic and manual
mode in the slide bar, or by pressing and holding the rotary knob.

Sea clutter

Sea clutter is used to filter the effect of random echo returns from waves or rough water near
the vessel.

When you increase Sea clutter, filtering the on-screen clutter caused by the echoes of waves
is reduced.

The system includes predefined Sea clutter settings for harbor and offshore conditions for all
radar systems except Halo, in addition to the manual mode where you can adjust the
settings. For all radar systems except Halo, you select Sea clutter modes from the menu, or by
a long press on the rotary knob. You can only adjust the Sea clutter value in manual mode.

Auto Sea Offset

To allow fine tuning of the Sea control while in Auto mode (Auto uses directional adaptive
clutter rejection), the Auto setting may be offset.

Rain clutter

Rain clutter is used to reduce the effect of rain, snow or other weather conditions on the
radar image.

The value should not be increased too much as this may filter out real targets.

Using the cursor on a radar panel

By default, the cursor is not shown on a radar panel.
When you position the cursor on the radar panel, the cursor position window is activated.

Go to cursor

You can navigate to a selected position on the image by positioning the cursor on the panel,
and then using the go to cursor menu option.

The cursor assist function

Note: The cursor assist function is available if it is enabled. Refer to "Customizing the long press

Ú

feature" on page 18.

The cursor assist function allows for fine tuning and precision placement of the cursor
without covering details with your finger.

Activate the cursor on the panel, then press and hold your finger on the screen to switch the
cursor symbol to a selection circle, appearing above your finger.

Without removing your finger from the screen, drag the selection circle to the desired
position.

When you remove your finger from the screen the cursor reverts to normal cursor operation.

Advanced radar options

Menu options can vary depending on your radar's capability.

78

Noise Rejection

Sets the amount of noise filtering applied by the radar. Target sensitivity is increased at
longer ranges when this control is set to Low or High, but does cause some loss of target
discrimination.

Note: To get maximum range performance from the radar, transmit on one range only,

Ú

set the Noise Reject control to High and the threshold as low as possible. The default is
30% for less clutter on the screen. In some areas where extreme high interference may
exist, try OFF for best radar image.

Radar| Zeus³S Operation Manual

Radar threshold

The threshold sets required signal strength for the lowest radar signals. Radar returns below
this limit are filtered and are not displayed.

Default value: 30%.

Target expansion

Target expansion increases the length of targets in range, making them easier to see.

Rejecting radar interference

Interference could be caused by radar signals from other radar units operating in the same
frequency band.

A high setting reduces the interference from other radars.
In order not to miss weak targets, the interference rejection should be set to low when no

interference exists.

Target separation

Controls the target discrimination of the radar (separation between objects is more
prominent).

Fast scan

Sets the speed of the radar antenna rotation. This option gives faster target updates.

Note: Maximum speed may not be achieved depending on the radar Settings, Mode,

Ú

and Range selected. The radar will only rotate as fast as the current control settings allow.

Sea State

Set the Sea State control according to current sea conditions for best sea clutter rejection.

Target boost

The target boost control increases pulse length or reduces radar bandwidth to make targets
appear larger in range and increase radar sensitivity.

Radar view options

View menu options vary depending on your radar antenna.

VelocityTrack

Note: When VelocityTrack is enabled antenna rotation speed may be reduced.

Ú

Note: When operating the radar in Dual range mode with one of the ranges set to 36

Ú

nm or more, increased VelocityTrack coloring noise over land areas may be seen.

Doppler coloring is a navigation aid to distinguish moving targets approaching or diverging
from your vessel. The radar indicates if a target is approaching or diverging from your vessel
when both these conditions are true:

• The target's relative speed is greater than the VelocityTrack speed threshold.

• The target is not geo-stationary (e.g. land or a marker buoy).

The following options are available:

• Off - turns off Doppler coloring

• Normal - approaching targets and diverging targets are colored.

• Approaching targets - only approaching targets are colored

The color of approaching and diverging targets depends on the palette used:

• Diverging targets are blue colored on all radar image palettes.

• Approaching target colors on radar image palettes:

-

The speed threshold can be defined to apply for the radar source of the selected radar panel

only, or to all radar sources connected to the system. The setting is only applied to those
radars powered and connected at the time the setting is made. If the all radar sources option
is selected, newly connected radars will use the specified values automatically.

VelocityTrack examples

Approaching and diverging moving targets can be indicated as neutral (not colored) in some
circumstances. The navigator should be aware of these situations to safely use the
VelocityTrack feature as an aid for collision avoidance.

Examples of how VelocityTrack behaves in 2 navigation scenarios is illustrated below. The
illustrations show a target (A) crossing own vessel's (B) path.

The examples show the target movement (1-5) over 5 radar scans with the radar in relative
motion mode.

In example C, own vessel COG is 0°, and speed is 0 knots.
In example D, own vessel COG is 0°, and speed is 10 knots.
In both examples, the target COG is 270°, and the speed is 20 knots.
The colors in the examples are according to the colors used for black/green and black/yellow

radar palettes:

• Red (C1/C2 and D1/D2), indicating the target is on an approaching path to own vessel. Its

relative speed at that point is greater than the VelocityTrack speed threshold.

• Not colored (C3 and D3/D4), indicating it is temporarily neutral because its relative speed

at that point is less than the VelocityTrack speed threshold.

• Blue (C4/C5 and D5), indicating the target is diverging away from own vessel and its

relative speed at that point is greater than the VelocityTrack speed threshold.

Radar symbology

the radar panel illustration showing optional radar items.

Radar| Zeus³S Operation Manual

Target trails

You can set how long the trails generated from each target on your radar panel remain. You
can also turn OFF target trails.

Note: True motion is recommended when using Target trails

Ú

Clearing target trails from the panel

When target trails are displayed on the panel, the radar menu expands to include an option
where you can clear target trails from your radar panel temporarily. The target trails start to
appear again unless you switch them off as described above.

The radar palette

Different colors (palettes) can be used to represent detail on your radar panel.

Radar orientation

Radar orientation is indicated on the upper left corner of the radar panel as either HU
(Heading UP), NU (North Up) or CU (Course up).

Head-up

In head-up mode, the heading line on the PPI is oriented on the 0° on the bearing scale and
towards the top of the screen. The radar image is displayed relative to own ship, and when
the ship turns the radar image rotates.

Note: Head-up is only available in relative motion mode, and it is the only orientation

Ú

mode available if the radar is not connected to a heading source.

North up

In North up mode the 0° indication on the PPI represents north. The heading line on the PPI
is oriented according to own ship heading obtained from the compass. When the ship turns
the heading line changes its direction according to the ship's heading, while the radar image
remains stabilized.

The North up orientation is not available if no heading source is connected to the radar. If
heading data is lost, the system will automatically switch to Head-up orientation.

Course up

In Course up mode, the top of the bearing scale indicates the ship’s true course measured
from north at the time Course up was activated. When the ship turns the bearing scale
remains fixed, while the heading line rotates with the ship's yawing and course change.

The Course up orientation is reset by re-selecting the Course up mode.

Radar motion mode

Radar motion is indicated on the upper left corner of the radar panel as either TM (True
motion) or RM (Relative motion).

Relative motion

In relative motion your vessel remains in a fixed location on the Radar PPI, and all other
objects move relative to your position.

You select the position of the fixed location as described in "Offsetting the PPI center" on page 82.

True motion

In true motion your vessel and all moving targets move across the Radar PPI as you travel. All
stationary objects remain in a fixed position. When the vessel’s symbol reaches 75% of the
PPI radius (A), the radar image is redrawn with the vessel symbol re-positioned (B) 180°
opposite the current heading bearing.

Radar| Zeus³S Operation Manual

81

B

When true motion is selected, the true motion reset option is available from the menu. This
allows for manually resetting the radar image and vessel symbol to its starting position.

Note: True motion is only available when the PPI is in either north up or course up

Ú

orientation mode.

Offsetting the PPI center

You can set the antenna position origin to a different location on the radar PPI. The options
described in the next sections are available.

PPI center: Center PPI center: Look Ahead PPI Center: Offset

Note: The bearing scale is according to the Consistent Common Reference Point (CCRP),

Ú

while the offset sets the radar antenna position on the PPI. The maximum off-centering
allowed is 75% of the radius at the current range. This may result in the CCRP being
outside of the bearing scale. In such cases the measurements are still taken by the CCRP
and the bearing scale is compressed accordingly.

Center

The Center option resets the antenna position to the center of the PPI.

Look ahead

The Look ahead option is used to maximize the view ahead of the vessel. When selected the
PPI center is placed at 70% of the radius of the PPI, 180° opposite the top of the display.

Note: Look ahead is only available for Heading Up radar orientation.

Ú

Offset

This option allows you to use the cursor for selecting the PPI center.
Move the cursor to the preferred offset position, and confirm your selection.

EBL/VRM markers

The electronic bearing line (EBL) and variable range marker (VRM) allows quick
measurements of range and bearing to vessels and landmasses within radar range. Two
different EBL/VRMs can be placed on the radar image.

The EBL/VRMs are by default positioned from the center of the vessel. It is, however, possible
to offset the reference point to any selected position on the radar image.

When positioned, you can turn the EBL/VRM on/off by selecting the relevant markers on the
data bar, or by deselecting the marker from the menu.

About AIS

If a compatible AIS (Automatic Identification System) is connected to the system, AIS targets
can be displayed and tracked. You can also see messages and position for DSC transmitting
devices within range.

AIS targets can be displayed as overlay on chart and radar images.
The AIS is an important tool for safe travelling and collision avoidance. You can set alarms to

notify you if an AIS target gets too close or if the target is lost.

AIS vessels on a chart panel AIS vessels on a radar panel

Selecting an AIS target

When you select an AIS icon, the symbol changes to selected target symbol. Only one target
can be selected at a time.

Note: Pop-up information must be enabled to see the vessel's name. Refer to "Chart

Ú

settings" on page 32.

Searching for AIS vessels

You can search for AIS targets by using the find option in the menu. If the cursor is active, the
system searches for vessels around the cursor position. Without an active cursor, the system
searches for vessels around your vessel's position.

Displaying target information

The vessels dialog

The vessels dialog displays a list of all targets.
By default, the dialog lists targets, arranged by distance to own vessel. You can select to

change the sort order, and to display only a selected target type.

• select the info option in the menu

AIS| Zeus³S Operation Manual

AIS information on radar panels

The radar data bar includes information about targets.
The targets are listed with the closest target on top, and are color coded to indicate target

status.

Calling an AIS vessel

If the system includes a VHF radio supporting DSC (Digital Select Calling) calls over NMEA
2000 or NMEA 0183, a DSC call can be initiated to other vessels from the unit.

The call option is available in the AIS vessel details dialog, and in the vessel status dialog.
Refer to "Displaying target information" on page 86.

DSC Vessel tracking

DSC (Digital Selective Calling) is a semi-automated method of requesting or receiving
position data from a vessel with a DSC VHF radio. For more information on how to use this,
refer to your VHF radio manual.

There are various types of DSC position messages, including distress calls. The type of
message made determines information sent with the call, and how the radio and MFD
respond to the incoming call.

When a DSC message has been received, the MFD will display a DSC vessel icon
on the chart panel and radar panel at the received coordinates. In addition, some
radios will send COG and SOG with the position data. This allows for correct
orientation of the icon.

When receiving a distress message you will see an alarm box informing you that a message
has been received. This can be read under the messages tab on the vessels dialog. Select the
vessels button in the toolbar to display the vessels dialog.

AIS SART

When an AIS SART (Search and Rescue Transponder) is activated, it starts transmitting its
position and identification data. This data is received by your AIS device.

If your AIS receiver is not compliant with AIS SART, it interprets the received AIS SART data as
a signal from a standard AIS transmitter. An icon is positioned on the chart, but this icon is an
AIS vessel icon.

If your AIS receiver is compliant with AIS SART, the following takes place when AIS SART data
is received:

• An AIS SART icon is located on the chart in the position received from the AIS SART

• An alarm message is displayed

If you have enabled the siren, the alarm message is followed by an audible alarm.

Note: The icon is green if the received AIS SART data is a test and not an active message.

Ú

AIS SART alarm message

When data is received from an AIS SART, an alarm message is displayed. This message
includes the AIS SART’s unique MMSI number, and its position, distance, and bearing from
your vessel.

AIS| Zeus³S Operation Manual

87

You have the following options:

• Ignore the alarm

-

The alarm is muted and the message closed. The alarm does not reappear

Note: If you ignore the alarm, the AIS SART icon remains visible on your chart, and the

Ú

AIS SART remains in the vessels list.

• Save the waypoint

- The waypoint is saved to your waypoint list. This waypoint name is prefixed with MOB
AIS SART - followed by the unique MMSI number of the SART. For example, MOB AIS
SART - 12345678.

• Activate the MOB function

- The display switches to a zoomed chart panel, centered on the AIS SART position

- The system creates an active route to the AIS SART position

Note: If the MOB function is already active, this will be terminated and replaced by the

Ú

new route towards the AIS SART position.

Note: If the AIS stops receiving the AIS SART message, the AIS SART remains in the

Ú

vessels list for 10 minutes after it receives the last signal.

Vessel alarms

You can define several alarms to alert you if a target shows up within predefined range limits,
or if a previously identified target is lost.

Ú

Frequency

The unit supports several transducer frequencies. Available frequencies depend on the
transducer model that is configured for use.

Echosounder| Zeus³S Operation Manual

93

• A low frequency, for example 50 kHz, will go deep. It generates a wide cone but is more

sensitive to noise. It is good for bottom discrimination and wide area search.

• A high frequency, for example 200 kHz, offers higher discrimination and is less sensitive to

noise. It is good for separating targets and for higher speed vessels.

Gain

The gain controls the sensitivity. The more you increase the gain, the more details are shown
on the image. However, a higher gain setting may introduce more background clutter. If the
gain is set too low, weak echoes might not be displayed.

A manual and an automatic gain mode are available. By default, the gain is set to Auto.

Color

Strong and weak echo signals have different colors to indicate the different signal strengths.
The colors used depend on which palette you select.

The more you increase the color setting, the more echoes are displayed in the color at the
strong return end of the scale.

Source

Note: Available only if multiple sources with the same capability are available.

Ú

With dual sonar capability a sonar/CHIRP and a ForwardScan transducer can be connected
directly to the unit.

The ForwardScan transducer must be connected to a compatible sonar module (or another
unit which has built-in sonar shared over the network).

If you have both a sonar/CHIRP and a ForwardScan transducer connected to different sonar
modules (or another unit which has built-in sonar shared over the network), you can view
both simultaneously on a single device.

Warning: Do not rely on this equipment as your principle source of

navigation or hazard detection.

Warning: Do not use this equipment to gauge depth or other conditions

for swimming or diving.

Setting up the ForwardScan image

Source

Note: Available only if multiple sources with the same capability are available.

Ú

Used to specify the source for the image in the active panel.
You can display different sources simultaneously, using a multi-panel page configuration.

Menu options for each panel are independent.

Note: Using transducers at the same frequency can cause interference.

Ú

For source setup information, refer to the Zeus³S Installation Manual.

Depth

Controls depth range. Depth range is set to auto mode by default.

Forward range

Controls the forward looking search range. Maximum Forward range is 91 meters (300 feet).

Noise rejection

Filters out signal interference and reduces on-screen clutter.

Show zones

Displays warning zones (yellow) and critical zones (red) on the screen. Refer to "Critical forward
range and Critical depth" on page 101.

More options

Pause

Pauses the image, allowing you to examine the image in detail.
The pause function stops the echosounder from pinging. The system is not collecting data

when paused in this manner.

Palettes

Used for selecting the image's color palette.

History ratio

Controls how much sounder history is shown behind the boat. The higher the ratio, the more
history will be shown.

Point data

By default, ForwardScan only shows the bottom. Select this option to specify to view no
sounder data points, all data points, or only points (objects) in the water column.

Depth lines

Displays lines on the screen that make it easier to quickly estimate depth and the underwater
objects.

Recording ForwardScan data

Displays the record dialog. ForwardScan log data can be recorded by selecting the correct
file format (sl3) in the record dialog. For more information, refer to "Recording log data" on page

92.
