  • Magneto-inductive positioning using a rotating magnetic field
    Patent number: 9002675
    Abstract: A method and system for locating the position of a source that emits a rotating magnetic field. Three or more receivers are deployed or positioned in known position relative to each other, which may be along a common axis in some cases. Phase differences between the magnetic fields measured by the receivers are detected. The phase shifts are used to determine the location of the source. With three receivers, a range and bearing angle relative to a middle receiver may be determined. With five or more receivers, a range and two bearing angles may be determined, thereby providing a three-dimensional position.
