POSITIONING ERROR CALCULATION DEVICE, POSITIONING ERROR CALCULATION SYSTEM AND POSITIONING ERROR CALCULATION METHOD

摘要

Provided is a positioning error calculation device which enables provision of an appropriate positioning error value regarding position data obtained by base-station positioning regardless of the position where a positioning target exists. The positioning error calculation device includes: an element which stores therein positioning record information including first positioning result information corresponding to a position of a terminal device; an element which selects and acquires the positioning record information; an element which calculates a density of positioning records at each of predetermined places on the basis of the positioning record information; an element which calculates an estimated positioning error value by using a relational expression, on the basis of the density; and an element which acquires the estimated positioning error value at each of the places by acquiring the estimated positioning error value corresponding to the density at the each of the places.
