D PAST POSITION
In addition to their symbol, all acquired targets can be given a history track.
With the PAST POSITION function switched on, a past position point is set at
the target symbol’s position (see Figure: 2−30).
The interval between two past positions can be adjusted.
Past positions indicate the last completed maneuver of the acquired
targets. In absolute (TRUE) view, it is possible to differentiate between
changes of course and changes of speed.
