PURPOSE: A measuring position method and the system using the multi station information can reduce error toward the location of the moving body. CONSTITUTION: A receiver(210) receives a message signal toward the coordinate of station. The electric field strength measuring part(220) measures the electric field intensity of signal. The coordinate estimating unit(230) uses coordinate and electric field intensity of the station. The coordinate of the moving body is presumed. The reliability calculation unit(250) calculates the reliability toward the coordinate estimation result of the moving body.
