This positioning device includes: a first positioning means that measures the position of the positioning device at prescribed time intervals; a second positioning means that measures the position of the positioning device with lower accuracy than the first positioning means and at time intervals that are shorter than those used by the first positioning means; a correction means that corrects the measurement results of the second positioning means on the basis of the position measured by the first positioning means at a prescribed point in time and the position at the prescribed point in time obtained from the measurement results of the second positioning means; and a generation means that, on the basis of the measurement results of the first positioning means and the measurement results of the second positioning means as corrected by the correction means, generates path information indicating the path of movement of the positioning device. |
