Combining the Same MARPA and AIS Target

If you are using both MARPA and AIS, you might notice that sometimes the same target is identified by both systems, which may clutter the radar screen. To prevent this, the chartplotter can combine the targets to reduce the number of items shown at the same time.

  1. From a radar screen, select Options > Layers > Other Vessels > Target Association.

    The system evaluates the position, speed, and course of all MARPA and AIS targets, and combines the targets it determines to be the same.

  2. Select Menu button > Target Display to set whether the system uses MARPA or AIS to identify the combined target on the screen.
