Patent attributes
The method estimates movement of a solid mobile in a medium capable of generating disturbances defined by a three-variable vector, wherein the movement is defined by a six-variable vector and the solid is equipped with at least one sensor sensitive to acceleration having at least three sensitive axes and at least one sensor sensitive to the magnetic field having at least three sensitive axes. The method for estimating the movement of a solid includes a step of calculating a nine-variable vector consisting of the six-variable movement vector and of the three-variable disturbance vector and a step of weighting the nine-variable vector capable of transforming the nine-variable vector into a vector with not more than five variables to be estimated.
