Abstract
A method for estimating the movement of an object moving in an ambient magnetic field. The method acquires at least one component of the magnetic field and/or an i-th derivative of the magnetic field measures at least one item of information representative of the movement of the object; evaluates the stationary or otherwise character of the magnetic field; estimates at least one component of the movement of the object using at least one equation other than magnetic linking the component of the movement of the object and the at least one acquired item of information representative of the movement of the object depending on the result of the evaluation at least one magnetic equation linking the component of the movement of the object and the at least one acquired component of the magnetic field and/or an i-th derivative of the magnetic field.
