Abstract
Official abstract text for this publication.
Provided are a method and apparatus for measuring a location of a terminal using a magnetic field. For example, the apparatus may measure a location of a terminal using a magnetic field obtained by a magnetic field sensor and one or more sensor values obtained by a plurality of other sensors.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of measuring a location of a terminal using a magnetic field, the method comprising: receiving a magnetic field map of an area at which the terminal is located, wherein the magnetic field map includes a size of a magnetic field and a magnetic north direction; receiving values sensed by a first sensor and a second sensor which are included in the terminal and which sense a first information and a second information, respectively; and measuring a…
