Past Position Display

The past position display shows equally time-spaced dots marking past positions
of activated AIS targets. A new dot is added at preset time intervals until the
preset number is reached. If a target changes its speed, the spacing will be
uneven. If it changes course, its plotted course will not be a straight line.
Note that AIS past positions will be shown if TARGET TRACK on the DISPLAY
sub menu of the PLOTTER menu is ON, regardless of whether AUTO TARGET
TRACK on the PLOTTER menu is turned ON or OFF.
