Abstract
Disclosed herein are a location estimation apparatus and method using a combination of different positioning resources. The location estimation apparatus includes a motion model generation unit for generating a motion model corresponding to a state variable of a terminal based on a current time, a weight calculation unit for extracting a dynamic location database (DB) from a location DB based on multiple pieces of measurement information received from the terminal, and calculating a weight proportional to a likelihood of the multiple pieces of measurement information based on the dynamic location DB, and a location estimation unit for estimating a location and direction of the terminal by applying the weight to at least one sample value corresponding to the motion model.
