Fixed range rings or a map grid can be displayed. Range rings are concentric circles with the reference
position as their centre, and are situated at equal distances from one another.

Own Ship Symbols and Target Symbols, Vectors, Past Position Plots
Own Ship Symbol
The own ship symbol consists of two concentric circles
. In the
smaller display ranges up to and including 1.5 NM, the circles are
replaced by an own ship contour, whose length and width are true
to scale.

The own ship symbol is supplemented by the following elements:.
-
Heading line: It is the extension of the ship’s longitudinal axis
in the ahead direction and extends to the edge of the PPI. The
heading line is displayed at all times.

Speed vector: The direction of the vector corresponds to the
existing course of own ship. The length corresponds to the
existing speed of own ship. Together with the speed vectors of
the tracked radar targets, the display of the speed vector can be
switched on and off, and the time represented by the displayed
vectors can be specified. Furthermore, it can be seen from the
vector symbol of own ship whether the vector is relative to the
sea (Water Track, WT = one arrow-head) or relative to the
bottom (Bottom Track, BT = two arrow-heads).

position plot corresponds to the past movement of own ship. On
it, there are four time markers, whose distance apart in time can
