MARPA

The Mini Automatic Radar Plotting Aid or MARPA function is used

to aid in collision avoidance. MARPA can track up to ten designated

targets. Detailed information including Bearing, Range, Course,

Speed, Closest Point of Approach, and Time to Closest Point of

Approach for each target is displayed in the MARPA list.

Note: The MARPA function requires the use of a heading sensor.

The heading sensor must output the NMEA sentence HDM or

HDG at format 0183, v2.30 or higher.

MARPA relies on a Heading Sensor to provide accurate own vessel

heading information. Accurate heading data enhances MARPA's

performance. Each target being tracked by MARPA is represented by

a symbol. The symbols indicate the current state of the target.
