Title:
METHOD AND SYSTEM FOR DETERMINING HEAVE AND HEAVE RATE OF VESSELS
Document Type and Number:
WIPO Patent Application WO2003101826
Kind Code:
A3
Abstract:
A method for determining heave and heave rate for a vessel (40) is described. The vessel (40) includes an inertial navigation system (INS) (10), and sensors (22) for the INS (10) being located at a point A of the vessel (40), the vessel (40) having a zero heave reference point B, and the described method provides heave and heave rate at a point C of the vessel (40). The method includes determining reference coordinates for points A, B, and C of the vessel (40), generating a velocity signal representative of a velocity at a point on the vessel (40), generating a heave rate signal based upon the velocity signal, and generating a heave based upon the heave rate signal.
