Abstract

Provided are a method and an 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.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2011-0088796 filed with the Korean Intellectual Property Office on Sep. 2, 2011, the entire disclosure of which is hereby incorporated by reference for all purposes. technical field [0002] The following description relates to methods and apparatuses for measuring the location of a terminal based on a magnetic field. Background technique [0003] Methods for measuring the position of a terminal in an indoor environment include, for example, a scheme using a wireless local area network (LAN) signal or a wireless fidelity (Wi-Fi) signal, a scheme using an ultrasonic signal, a scheme using an ultra-wideband (UWB) signal Wait. However, these solutions have many disadvantages. [0004] For example, schemes using wireless LAN or Wi-Fi signals have extremely low accuracy, and schemes using ultrasonic signals and UWB signals incur high costs due to indoor infrastructure. [0005] Another disadvantage of...
