A position estimation system and a method thereof are provided to shorten a development time by simplifying a position estimation algorithm using an encoder and an accelerometer. A position estimation system comprises an accelerometer(10) for detecting bidirectional acceleration of a movable member, at least one encoder(20) for detecting a moving distance of the movable member, an analyzing module(30) for calculating a speed and a rotation angle based on the accelerometer and the encoder, a correction module(50) for calculating a corrected speed and a corrected rotation angle, and a position estimation module(60) for estimating the position of the movable member based on the corrected speed and a corrected rotation angle.
