ARPA - Automatic Radar Plotting Aids - an attribute that enables
radar sets to track objects with course and speed information.
The objective is to use the information to avert collision between
vessels.
When the Andrea Doria and
Stockholm collided, it was
described by some as a
"radar-assisted collision".
