Abstract
A computer executes processing of acquiring, by using a positioning unit to output error region information indicating an ellipse-shaped error region represented by a position acquired from positioning performed by receiving a signal from a plurality of transmitters and a measurement error of the position, a plurality of pieces of the error region information by performing the positioning a plurality of times, processing of extending the error region indicated by each piece of the acquired error region information in a major axis direction, and processing of estimating a position of a positioning target based on an intersect region at which the extended error regions intersect with one another.
