Abstract	Analysis of four-frequency satellite Doppler data has allowed the separation and measurement of frequency-dependent ionospheric contributions to the Doppler shift, providing information useful in the study of errors incurred when tracking radio signals through the ionosphere. These refraction errors affect the accuracy of navigational position fixes obtained by Doppler satellite tracking systems. Some measured ionospheric refraction errors reported here are of interest because their magnitudes are significantly greater than those heretofore predicted from theoretical considerations.
