<p>PROBLEM TO BE SOLVED: To reduce a positioning error of propagation delay, caused by an ionospheric layer, in a region with great fluctuation of the ionospheric layer, and to improve positioning accuracy.SOLUTION: In the correction method of the present invention, calibration information of propagation delay caused by the ionospheric layer transmitted from a master station to a user station is generated by using only a positioning signal of a navigation satellite, each existing according to a direction seen from a monitoring station, individually for each direction. The user station corrects the positioning signal from the navigation satellite using the calibration information of the propagation delay caused by the ionospheric layer independent of the direction to perform positioning of the own station.</p> |
