<p>Provided is a positioning error calculation device enabling an appropriate positioning error value of position data obtained by base station positioning to be provided regardless the position where an object to be positioned is present. The positioning error calculation device comprises: a first positioning record holding means for holding first positioning record information including first positioning result information corresponding to the position of a terminal device measured by a first positioning means; a record selecting means for selecting and acquiring first positioning record information from the first positioning record holding means; a positioning record density calculating means for, based on the first positioning record information acquired by the record selecting means, calculating positioning record density for each place; a density and positioning error calculating means for, based on the density calculated by the positioning record density calculating means, calculating an estimated positioning error value from a relational equation; and a position and positioning error calculating means for, based on the density for each place calculated by the positioning record density calculating means, acquiring, from the density and positioning error calculating means, the estimated positioning error value corresponding to the density and acquiring the estimated positioning error value for each place.</p> |
