Calculation accuracy of safe course made good in an anticollision system

The article presents an accuracy analysis of calc ulation made by a Multiagent Decision-Support System (MADSS) of navig t on. On the basis of messages received from Universal Ship-borne AIS system (Auto matic Identification System) the system calculates the parameters of vessels’ encoun ter a d works out the parameters of own vessel’s movement (course or speed), which lead to passing other objects according to a set CPA (Closest Point of Approach).
