To provide a position determining apparatus, speed determining apparatus and position determining method capable of further improving measurement accuracy.SOLUTION: A position determining apparatus 15 according to an embodiment, the position determining apparatus 15 for determining a position of a vehicle includes a first positioning section 21, a second positioning section 25 and a discrimination section 26. The first positioning section 21 receives a positioning signal from a satellite and determines a first position of the vehicle. The second positioning section 25 determines a second position of the vehicle based on an output of a self-supporting positioning sensor. In at least one case of a case where the first position is a range based on a prescribed position and a case where a change in a travel direction of the vehicle is a prescribed amount, the discrimination section 26 determines the second position as the position of the vehicle.SELECTED DRAWING: Figure 2

    【課題】計測精度をより向上可能な位置測位装置、速度測位装置、及び位置測位方法を提供する。【解決手段】実施形態に従った位置測位装置15は、車両の位置を測位する位置測位装置15であって、第1測位部21と、第2測位部25と、判別部26と、を備える。第1測位部21は、衛星からの測位用信号を受信し、車両の第1位置を測位する。第2測位部25は、自立測位用センサの出力に基づいて、車両の第2位置を測位する。判別部26は、第1位置が所定の位置に基く範囲である場合、及び車両の進行方向の変化が所定量である場合の少なくとも一方である場合に、第2位置を車両の位置とする。【選択図】図2
