3. PLOTTER OPERATION
3-8
3.2 Presentation Mode
Three types of presentation modes are provided for the plotter display: north-up, course-up
and auto course-up. To change the presentation mode, press the HIDE/SHOW key followed
by the MODE soft key. Each press of the key changes the presentation mode and
presentation mode indication (top right-hand corner of the screen) cyclically in the sequence
of North-up, Course-up and Auto course-up.
For C-map model, the sequence is North-up, Perspective, Course-up and Auto course-up
when PERSPECTIVE DISPLAY is set to ON, on the CHART DETAILS menu. (See Chapter
7.)
North-up
North (zero degree) is at the top of the display and own ship is shown with a filled circle.
This mode is useful for long-range navigation.
Course-up
The course-up mode is useful for monitoring
ship’s progress towards a waypoint. The
destination is at the top of the screen when a
destination is set. When no destination is set,
the course or heading is at the top of the screen
at the moment the course-up mode is selected.
A filled triangle marks own ship’s position.
Note: The data sentences GGA and VTG must
be output from the NavNet display unit
connected to the GPS navigator in order to
correctly orient the own ship marker in the
course-up mode on other NavNet display units.
Auto course-up
The course is at the top of screen at the moment
the auto course-up mode is selected. In this
mode, the current course is kept at the top of the
screen when the change is within 22.5 degrees.
For example, if your vessel turns larger than
22.5 degrees to port or starboard, the chart
display will rotate so that your course is pointing
towards the top of the screen again. A filled
triangle marks own ship’s position.
Perspective (C-map only)
Chart data is projected in perspective mode, for 3D
simulation, during navigation.
