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.
