Beacon-Based Geolocation Using A Low Frequency Electromagnetic Field
US Patent:
2013011, May 9, 2013
Filed:
Nov 7, 2011
Appl. No.:
13/290574

Assignee:
RAYTHEON COMPANY - Waltham MA
International Classification:
G06F 19/00, G01C 21/00
US Classification:
702152
Abstract:
A method of performing geolocation of receivers, transmitters, and conductive objects includes detecting, with one or more receivers, magnetic field signals generated by one or more transmitters, with each transmitter including two or more co-located coils that are electrically unstable and unbalanced, and that have a mechanically stable orientation with respect to one another. The magnetic field signals from each of the two or more co-located coils of each of the two or more transmitters are decomposed into individual magnetic field components. A set of invariant scalar values that are independent of orientation of one or more magnetic antennas associated with the one or more receivers are calculated from the individual magnetic field components, and the position of an object is determined using the set of invariant scalar values.

International Classification:
G01B 7/14
US Classification:
32420711
Abstract:
A method of navigation includes receiving a magnetic field signal from a magnetic field transducer, the magnetic field signal proportional to sensed magnetic fields associated with magnetic field sources, in a processor, processing the magnetic field signal to determine magnetic field axes of rotation corresponding to rotations of the sensed magnetic fields, and using the magnetic field axes of rotation to render a position of the magnetic field transducer.
