Abstract
An apparatus for estimating the location of a terminal obtains definite location information of the terminal, estimates a dead reckoning location of the terminal using finally obtaining definite location information when definite location information of the terminal is not obtained for a set time, and combines positioning information of an adjacent terminal, definite location information of the terminal, and dead reckoning location information of the terminal with each other when reliability of dead reckoning location information of the adjacent terminal is higher than reliability of dead reckoning of the terminal to estimate combinatorial location information of the terminal.
