| 摘要 |
The invention concerns an electronic device for aid to navigation for ships such as military or commercial ships subjected to meteorological and/or operational constraints, comprising the following means: means for collecting data such as meteorological data, loading data and operational constraint data; means for modelling the meteorological and operational context; means for modelling the ship's platform; means for modelling the swell/ship interactions based on criteria such as roll, pitch, structural deformation, heave, relative bearing and relative wind force; means for determining the admissible navigation zones for the ship in terms of course/speed, for each of the criteria used for modelling swell/ship interactions; means for determining the operable zones for the ship by combining the admissible zones of at least two criteria. The invention also concerns a method using such a device.
