A method for calculating the surface (water surface) speed of at least one ship, and a method for estimating each drift (floating) vector at all points in the route of the ship.

摘要

The present invention relates to a method for calculating a surface (water surface) vector of at least one ship that is navigating at a cruising speed by an engine. It comprises the following steps (it is a method). a) obtaining parameters including position, bow direction, reference (setting) speed, reference (setting) course of the vessel (1); b) means outside the vessel (1). Obtaining measurements (values) using and selecting from wind and tidal current measurements, which are measurements obtained from wind and tidal currents in the vicinity of the ship (1) c) obtained by step b) Determining the drift vector by one or more measurements (values) selected from wind and tidal measurements d) position, reference (on setting) speed, reference (on setting) course and Determine a reference (setting) vector based on parameters selected from those obtained from step a) e) Calculate the size and direction of the surface (water surface) vector of the ship (1) Figure 3
