2.32 CCRP (Common Consistent Reference Point)
The reference position for measurements (range, bearing, etc.) and markers (heading
line, stern mark, etc.) can be antenna position or CCRP, which is a location on own
ship to which all horizontal measurements, for example range, bearing, relative
course, relative speed, closest point of approach (CPA) or time to closest point of ap-
proach (TCPA), are normally referenced.
To select the reference position, click the button below [REF point] at the top-left po-
sition to select [ANT] or [CCRP] as applicable.
