Charts
The chart function displays your vessel’s position relative to land and other chart objects.
On the panel you can plan and navigate routes, place waypoints, overlay a radar image or
weather information, and display AIS targets.
The NSS has diff erent embedded cartography depending on region. Units sold in America will
include Insight cartography, while units sold in other regions will have embedded Navionics
coastal (Silver) cartography split by region. All units will support Navionics Platinum Plus and
TurboView via micro-SD Card slot accessible from the front of the unit.
Charts are shared over the network, so only one chart card per boat is required.
The fi rst part of this section describes how to use the charts, and is common to both Insight
and Navionics. Chart options depend on which cartography is in use on the unit. These are
covered in a separate section.

Magnetic variation
Magnetic variation is the diff erence between true bearings and magnetic bearings, caused by
diff erent location of the Geographic and the Magnetic north poles. Any local anomalies such
as iron deposits might also aff ect the magnetic bearings.
Magnetic variation is applied in order to navigate with heading in “True” mode.
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.
Datum
Most paper charts are made in the WGS84 format, which also is used by the NSS system.
If your paper charts are in a diff erent format, you can change the datum settings accordingly
to match your paper charts.
Coordinate system
Several coordinate systems can be used to control the format for lat./lon coordinates
displayed on the chart panel.

The course line
When travelling on a route the course line shows the intended course from one waypoint
towards the next.
When navigating towards a waypoint (cursor position, MOB or an entered lat/lon position),
the course line will show the intended course from the point at which navigation was started
towards the next waypoint.
Vessel symbol
The vessel symbol indicates distance and bearing relative to the intended course.
O course limit
If the XTE exceeds the defi ned off course limit (Refer “Steering alarm limits” on page 25), this
will be indicated with a red arrow including the distance from the track line.
If the off course alarm is enabled, the alarm will activate if the XTE exceeds the defi ned off
course limit.
Position panels
By default, there is one position panel available showing GPS position.
If Loran is enabled as described on page 26, there will be two position panels. This is
indicated with arrow symbols on left and right side of the panel.
You toggle between the panels by tapping the left or right side of the panel.

28 | Using the autopilot | NSS Operator Manual
Using the autopilot
If an AC12, AC42 or SG05 autopilot computer is connected to the system, autopilot
functionality will be available in the NSS.
An Autopilot is designed to maintain an accurate course in various sea conditions with
minimal helm movements.
Safe operation with the autopilot
Warning: An autopilot is a useful navigational aid, but DOES NOT
under any circumstances replace a human navigator.
Switching from automatic mode to manual steering
You can switch the autopilot to STBY mode from any automatic operation mode by a short
press on the STBY/AUTO key.
Note: If the NSS is connected to an EVC system via the SG05, you can take manual control of
the steering irrespective of the autopilot mode. Refer “Using the autopilot in an EVC system”
on page 38.
Activating the autopilot
You can activate the autopilot from any panel as shown below.
The autopilot pop up
You can only enable the autopilot once the pop-up is displayed.
anual adjustments to the set heading can only be made when the
port and starboard indicators are illuminated red and green - this is
done by pressing the rotary knob, or by tapping the autopilot pop-up.
The autopilot popup shows active mode, heading, rudder and various
steering information depending on active autopilot mode.
The pop-up has a fi xed position on the page, and it can be shown on all pages except when
an Autopilot panel is active.
You remove the pop-up from a page by tapping the in the upper right corner or by
pressing the X key.
Autopilot mode indication in top of the page
Autopilot information is by default shown in top of the pages when the Autopilot pop-up is
not displayed.
You can select to turn this information off .
Compass symbol on the chart panel
You can select to show a compass symbol around your boat on the
chart panel. The compass symbol will be off when the cursor is active
on the panel.

Using the autopilot | NSS Operator Manual
Controlling steering performance in automatic modes
The autopilot should be confi gured during installation and setup. Some parameters may
be adjusted during operation to increase the steering performance. Refer to “The autopilot
settings panel” on page 39.
Using the autopilot in standby mode
The autopilot must be in STBY mode when you steer the boat
manually.
You can switch the autopilot to STBY mode from any operation by a
short press on the STBY/AUTO key.
Power steering (NFU)
If you tap the PORT or STBD key icons in the pop-up dialog when the
autopilot is in STBY mode, the system will switch to NFU (Non-Follow-
Up). You can then use the key icons to control the rudder, and the
rudder will move as long as the key is pressed.
You return to STBY mode by a short press on the STBY/AUTO key.
Follow-up steering (FU)
You can select Follow-up steering from the Autopilot menu.
When FU is active you can use the rotary knob to set rudder angle.
The set angle is indicated by the yellow pointer above the rudder
angle graphic. The rudder will move to the commanded angle and
then stop.
Warning: While in Follow-up mode you cannot take manual control of the wheel.
You return to STBY mode by a short press on the STBY/AUTO key.
AUTO mode (auto compass)
When the AUTO key is pressed, the autopilot selects the current boat
heading as the set course. The yellow arrow shows the vessel’s actual
heading. If the arrow is pointing directly upwards, the vessel is on
course.
The autopilot will keep the boat on the set course until a new mode
is selected or a new course is set with the course knob or the PORT or
STBD key icons.
Once the course is changed to a new set course, the boat will automatically turn to the new
heading and maintain the new course.
Heading capture
When in AUTO or NoDrift mode the heading capture feature allows you to automatically
cancel the turn you are in by an instant press on the rotary knob. The autopilot will cancel the
turn to continue on the heading read from the compass the very moment you pressed the
rotary knob. This is a useful feature if you are not sure of the exact turn you have to make to
steer towards e.g. an inlet or a dock.
Turn pattern steering (power boats)
The autopilot includes a number of automatic turn steering features for power boats when
the pilot is in AUTO mode.
The turn steering option will not be available if the boat type is set to sailboat - instead the
tack/gybe feature is implemented.
32 | Using the autopilot | NSS Operator Manual
Initiating a turn
The illustration below shows how you start the spiral turn steering from the Autopilot menu.
You select the turn direction and start the turn by tapping the left or right keys or by using
the rotary knob.
Stopping the turn
You can at any time during a turn press the AUTO/STBD key to return to standby mode and
manual steering.
Turn variables
All turn steering options, except the C-turn, have settings that you may adjust before you start
a turn and at any time when the boat is in a turn. Refer to the example above.
U turn
U-Turn changes the current set course to be 180° in the
opposite direction.
The turn rate is identical to default rate of turn (ROT) setting.
This cannot be changed during the turn.
C-turn
C-turn makes the boat turn in a circle.
You can adjust the turn rate (ROT) before the turn is initiated
and during the turn. Increasing the turn rate makes the boat
turn a smaller circle.
Turn parameter Range Change per step Default Units
Rate of turn (ROT) 10 - 600 5 90 °/min
Spiral-turn
Spiral-turn makes the boat turn in a spiral with a decreasing or increasing radius. This feature
may be used for circling fi sh or when searching an object.
If the Change radius is set to zero, the boat will turn in a circle. Negative values indicate
decreasing radius while positive values indicate increasing radius.
