To efficiently calculate a position of a moving body.SOLUTION: A position calculation device includes: an orbit coordinate specification unit 52 for identifying two mutually adjacent facility coordinates from a side closest to positioning coordinates of a moving body by repeating processing of excluding a predetermined number of facility coordinates from a side of facility coordinates which are far from the positioning coordinates; and a kilometer calculation unit 53 for obtaining the kilometers of a position to which the positioning coordinates are assigned as a position of the moving body after correction in which the positioning coordinates are assigned on a line segment connecting the two identified mutually-adjacent facility coordinates.SELECTED DRAWING: Figure 1
【課題】移動体の位置を効率的に計算する。【解決手段】移動体の測位座標から遠い方の設備座標の側から所定個数の設備座標を除外する処理を繰り返して測位座標に最も近い方から2つの相互に隣り合う設備座標を特定する軌道座標特定部52と、特定された2つの相互に隣り合う設備座標どうしを結ぶ線分上に測位座標を割り付けるように補正したうえで移動体の位置として測位座標を割り付けた位置のキロ程を求めるキロ程計算部53と、を有する。【選択図】図1
