Abstract

In the following article we propose the method of using digital calculating machine of automatic radar plotting aids for calculating summary vector of the wind drift velocity and ship drift on the current and solving the inverse problem on combined the wind and the current account. The features mapping of gyrocompass course electronic line and line track angle of the ship taking into account the wind drift and ship drift on the current on the automatic radar plotting aids display are analyzed. The visual presentation of calculating summary vector of the wind drift velocity and ship drift on the current is given. Proposed method of solving the inverse problem on combined the wind and the current account is relevant in case of impossibility use the automatic control of the ship along a given trajectory when it is necessary continuous supervision for the navigational situation and the situation of convergence with another ships.
