1. A non-transitory computer-readable recording medium having stored therein a position estimation program for causing a computer to execute a process for estimating a position of a positioning target, the process comprising:

  • acquiring a plurality of pieces of error region information acquired by positioning performed plural times, by using a positioning unit to output the error region information indicating an ellipse-shaped error region represented by a position acquired from positioning performed after receiving a signal from a plurality of transmitters and a measurement error of the position,extending the error region indicated by each piece of the acquired error region information in a major axis direction, the error region having a proportion of a semi-major axis to a semi-minor axis equal to or greater than a first threshold andestimating the position of the positioning target based on an intersect region in which the extended error regions intersect with one another.
