PROBLEM TO BE SOLVED: To accurately estimate a position of a target node.SOLUTION: A position estimation system comprises: inertial position estimation means for estimating a first estimation position of a reception node on the basis of state change information detected by an inertial sensor provided in the reception node and absolute azimuth information, and obtaining first position change information indicating a time series change of the first estimation position; radio wave position estimation means for estimating a second estimation position of the reception node on the basis of intensity of a radio wave received from a transmission node in the reception node, and obtaining second position change information indicating a time series change of the second estimation position; and position correction means for comparing the first position change information with the second position change information and correcting the first estimation position according to the comparison result.SELECTED DRAWING: Figure 1
