Method for calculating the surface speed of at least one vessel and method for deducing each drift vector at every point on the path of said vessel
First Claim
1. A method for calculating surface vectors of a plurality of vessels, each vessel progressing under an engine at a cruising speed, in response to said each vessel in a predefined position, further comprising the steps:
- obtaining parameters of said each vessel including its position, its heading, its speed over ground and its course over ground from a remote sensor external to said each vessel;
obtaining at least one of wind and current measurements in proximity to said each vessel using the remote sensor external to said each vessel;
determining a drift vector for said each vessel by processing said at least one of wind and current measurements by a computer of a remote land-based center;
determining an over-ground vector for said each vessel by processing at least one parameter selected from the position, the speed over ground and the course over ground of said each vessel by the computer of the remote land-based center; and
simultaneously calculating a magnitude and a direction of the surface vector of said each vessel of said plurality of vessels under operational conditions progressing in a maritime area by the computer of the remote land-based center to monitor a maritime traffic over the maritime area.

Abstract
A method for calculating the surface vector of at least one vessel progressing under engine at cruising speed. When the vessel is in a defined position, the parameters of the vessel, including its position, its heading, its speed over ground and its course over ground, are obtained. Wind and/or current measurements in the proximity of the vessel are obtained using a device external to the vessel. The drift vector is determined from wind and/or current measurements. The over-ground vector is determined from the parameters selected from the position, the speed over ground and the course over ground of the vessel. The magnitude and the direction of the surface vector of the vessel is calculated.

16. A non-transitory computer readable storage medium comprising a series of instructions to calculate surface vectors of a plurality of vessels, each vessel progressing under an engine at a cruising speed, in response to said each vessel in a predefined position, said series of instructions executed by a computer of a remote land-based center causes the computer to:
-
obtain parameters of said each vessel including its position, its heading, its speed over ground and its course over ground from a remote sensor external to said each vessel; obtain at least one of wind and current measurements in proximity to said each vessel using the remote sensor external to said each vessel; determine a drift vector for said each vessel by processing said at least one of wind and current measurements; determine an over-ground vector for said each vessel by processing at least one parameter selected from the position, the speed over ground and the course over ground of said each vessel; and simultaneously calculate a magnitude and a direction of a surface vector of said each vessel of said plurality of vessels under operational conditions progressing in an maritime area to monitor a maritime traffic over the maritime area. - View Dependent Claims (17)
