Abstract The influence of ionospheric refraction on the output of interferometer is discussed and the method used to correct it is suggested. In the discussion the motion of sub-ionospheric point along the direction of declination is considered, and a new method to modify the value of f0F2 at sub-ionospheric point is proposed. Although these methods presented here are for correcting the ionospheric refraction of Miyun System, yet some ideas of these methods can be used in other cases.
