- Maritime CPA Application
Closest Point of Approach (CPA) is an estimated geographical point in which the distance between two maritime vessels or objects, of which at least one is in motion, will reach its minimum value, assuming no changes in course and speed are incurred by either object. The objects may be tracks, vessels or reference points. The Maritime CPA Application computes the distance, time and bearing for selected two Operational Objects, being one as the Master Reference, update periodically and present it graphically on the Geographical Display using Great Circle or Rhumb Line. Quick CPA is short calculation mechanism which will be valid for only a short time.
