Abstract
An apparatus comprises a magnetic target for generating a magnetic field that is uniform and concentric about a central axis of the target; an array of three-axis digital magnetic compasses for sensing the magnetic field; and a processor for finding intersection points of vectors from the compasses to the target. The vectors lie in a global X-Y plane that is normal to the central axis. Each vector indicates a direction of sensed magnetic field from one of the compasses to the magnetic target.
