AN ALGORITHM FOR AUTOMATED CONTROL OF THE POSITION OF THE EXTREMITIES OF SHIPS AND WAREHOUSES ON THE TRAJECTORY OF MOVEMENT BY MEANS OF ECDIS

Abstract

The article deals with the algorithm of control of the position of ships and warehouses on the trajectory, which solves the problem of automated high-precision control of the position of the extremities of ships and warehouses on the trajectory of motion by means of ESDIS. The algorithm of automated control of the position of the extremities of ships and warehouses on the trajectory, using the ECDIS coordinate cursor as a high-precision angular-rangefinder device, allows, when placed in the nose and stern of the vessel antennas GNSS receivers, to form on the EC their electronic markers with their coordinate cursors. These cursors can be used, when implemented automatically, using digital tracing systems (to the full coincidence of coordinate codes) and accompanying their finely controlled objects (geographical coordinates of which are in the electronic database) for high-precision automatic measurement of bearings and distances to underwater and of surface hazards in on-line modes for the purpose of controlling their position using the extremities of ships and warehouses relative to hazards with an accuracy comparable to the accuracy of GNSS operation in special ymah. Experimental studies, which were carried out by computer simulation, confirmed the high expected accuracy of the proposed algorithm, which is based on the same method.
