Abstract
Locating a moving magnetic object includes determining its position or orientation from measurements from an array N tri-axial magnetometers (N>5) mechanically linked to one another with 0-DOF by repeatedly estimating its position relative to the array from measurements made either in a preceding iteration or from a sensor distinct from the array's magnetometers before making a new measurement using the array's magnetometers; computing the distance between each magnetometer and the object's estimated position; eliminating Ni magnetometers closest to this estimated position, where Ni<N; using the remaining magnetometers, making a new measurement of the field generated or modified by the object; and determining its new position or orientation from the new measurements so as to obtain the object's new location.
