To evaluate positioning accuracy in a system for performing positioning by a satellite.SOLUTION: Disclosed is a positioning system for acquiring a positioning error of a positioning device for performing positioning based on positioning signals transmitted from a satellite. This system includes: detecting means for detecting that a vehicle has passed a fixed point whose coordinates are known; positioning means for storing a positioning result by the positioning device mounted on the vehicle in association with time information included in the positioning signal; and error acquiring means for acquiring the positioning error of the positioning device based on the positioning result corresponding to the detected time and the coordinates of the fixed point.SELECTED DRAWING: Figure 1

    【課題】衛星による測位を行うシステムにおいて、測位精度を評価する。【解決手段】衛星から送信された測位信号に基づいて測位を行う測位装置の測位誤差を取得する測位システム。座標が既知である定点を車両が通過したことを検知する検知手段と、前記車両に搭載された前記測位装置による測位結果を、前記測位信号に含まれる時刻情報と関連付けて記憶する測位手段と、前記検知がなされた時刻に対応する前記測位結果と、前記定点の座標と、に基づいて、前記測位装置の測位誤差を取得する誤差取得手段と、を有する。【選択図】図1
