Antenna Position
The antenna position may be displayed when own ship is in true scale only.
The antenna position is shown as a pair of small crossed lines, between
1mm and 2mm long, centred at the location on the
display corresponding to the position of the radar
antenna. Note that the antenna position may be in a
different location to the CCRP, as shown in the figure to
the right. For information on setting the antenna
position and CCRP, see `Top Unit Configuration' in
Chapter 1, `Configuration' of the Ship's Manual (Vol 2).
Own Ship Vector Controls
Vector Tick Marks
Tick marks can displayed along the vector length at one minute intervals,
with every sixth tick mark is shown with double thickness, for more details
see Own Ship Symbols.
To turn vector tick marks on or off tick or untick the
Display Vector Tick
Marks
check box.
To change the default tick mark interval time from 1.0 minute, left click in
the interval field, the value figure changes to green (editable). Move the
trackball left to decrease the time (0.1 minute minimum), or right to
increase the time (60 minutes maximum). Left click again to accept the
value and exit the editing process.
Vector Arrow Head
When the Display Vector Arrowhead check box is ticked the screen shows
the own ship's vector arrowhead (double arrowhead in ground stabilised
mode; single arrowhead in water stabilised mode).
Ground Stabilised Vectors
The default setting for ground stabilised vectors is Ownship vector
selected, see Own Ship Symbols. To turn predicted vector on tick the
Predicted Vector
check box. When predicted vector is selected the
ownship vector check box is automatically de-selected.
The default presentation, set at commissioning, is not to allow
Ownship Vector and Predicted Vector to be displayed
simultaneously. Although the option of simultaneous display may
be selected from the Configuration tool, this setting is NOT in
accordance with IEC 62388.
