A flying object flies in an outer space from the earth to the moon or a planet or near the moon or a planet. The flying object includes a positioning-signal reception device. A ground station includes a positioning-signal transmission device equipped with a directivity-direction control function and has known position coordinates in an earth-fixed coordinate system. The flying object measures position coordinates in the earth-fixed coordinate system by receiving a positioning signal transmitted from the ground station simultaneously from the ground stations at four locations.
