Embodiment Construction

[0023] Reference will be made to preferred embodiments of the invention with reference to the accompanying drawings. Although the following description includes specific details, it should be clearly understood by those skilled in the art that these specific details are provided to facilitate a thorough understanding of the invention and that modifications and variations can be made within the scope and spirit of the invention.

[0024] According to the present invention, Global Positioning System (GPS) location information refers to information indicating a location of a user terminal determined based on data received from GPS. The location information refers to information indicating a location of the user terminal estimated using information received from an acceleration sensor and a geomagnetic sensor. Indoor location information refers to: indicating that a wireless fidelity (Wi-Fi) positioning system (WPS) module, a cell-based location information providing module that p...

Abstract

A method and apparatus for providing location information are provided. The method comprises: location information is estimated; an error value of the estimated location information is calculated; activation of a location determination module is controlled according to the error value, and location information is provided using at least one of the estimated location information and the location information determined by a location determination module.

Description

technical field [0001] The present invention relates to a navigation technology, and more particularly, to a method and apparatus for determining location information in a blind zone of a Global Positioning System (GPS). Background technique [0002] The user navigation system uses GPS location information received from the GPS. However, when a user enters a GPS blind area where GPS signals cannot be received, the location of the user in the blind area is estimated based on valid GPS location information used before the user enters the blind area. [0003] Until the user moves out of the GPS blind zone and thus GPS position information becomes valid again (i.e., for the period of time the user stays in the GPS blind zone), traditional user navigation systems provide position information estimated by walking dead reckoning (PDR) or based on user A predetermined time and distance after entering a GPS blind zone provides limited location information. Or a traditional user nav...
