Abstract
A system and method are provided that allow for localization of a mobile device using detected magnetic signals and magnetic survey data. The magnetic signals may be produced by one or more magnetic signal sources, which are located at particular positions. The mobile device may be localized without information regarding the positions of the magnetic signal sources.
Claims20
A method comprising:
- receiving, at a mobile device, a magnetic signal having a signal bearing and signal strength;
- accessing magnetic survey data relating to previously recorded attributes of a magnetic field at a plurality of locations;
- comparing the previously recorded attributes of the magnetic field with the signal bearing and the signal strength of the magnetic signal;
- and
- determining, with a processor, a position of the mobile device based on the comparing step.
2 more elements
An system comprising:
- a detection device for receiving a magnetic signal having a signal bearing and signal strength;
- a memory for storing magnetic survey data relating to previously recorded attributes of a magnetic field at a plurality of locations;
- and
- a processor in communication with the detection device and the memory, the processor being configured to:
- perform a comparison of the previously recorded attributes of the magnetic field with the signal bearing and the signal strength of the magnetic signal;
- and
- determine a position of the detection device based on the performed comparison.
4 more elements
A method comprising:
- receiving magnetic survey data for a plurality of locations, wherein the survey data indicates a magnetic field attribute at each of the plurality of locations;
- storing the magnetic survey data;
- receiving signal data indicating a magnetic signal attribute;
- comparing the magnetic field attribute for one or more of the plurality of locations with the magnetic signal attribute;
- and
- based on the comparing step, determining, with a processor, a position for which the signal data corresponds.
