To obtain a positioning apparatus and a position estimation method for simultaneously estimating an accurate position of a fixed station and internal delay times of a mobile terminal and the fixed station if they are unknown, and facilitating an installation of the positioning apparatus.
The positioning apparatus for respectively estimating the positions of a plurality of the stations (1, 2) and the internal delay times included in communication processes within the stations includes an estimation means for respectively estimating the positions and the internal delay times of a plurality of the stations by solving a simultaneous equation for a plurality of the stations based on measurement results of a distance between two stations included in a plurality of the stations (1, 2) and a radio wave travel time defined by the internal delay times of two stations.
