Methods for calculating the surface vector and for calculating each deviation vector and computer program product

摘要

It is a method for calculating the surface vector of at least one vessel advancing by a cruising engine, distinguished by the fact that it comprises the following steps when said vessel (1) is in a position defined: a) obtain parameters of said vessel (1), including its position, its orientation, its speed over the ground and its course over the ground; b) obtain measurements, selected from wind and current measurements, using a medium external to said vessel (1), such measurements being obtained in proximity to said vessel (1); c) determining the deviation vector from one or more measurements obtained in step b), ie measurements selected from wind and current measurements; d) determine the ground vector from parameters selected from position, ground speed and ground course obtained in step a); and e) calculate the magnitude and direction of the vessel surface vector (1).
