Abstract
More than 320 passes of Viking S-X Doppler data have been used to investigate columnar content fluctuations in the solar wind from 19 August, 1976 to 28 February, 1977. These data are used to estimate the power spectrum and radial dependence of solar wind density fluctuations. It is found that: (1) the electron density fluctuations decline with heliocentric distance as r~1.8 * 9-1; (2) the power spectrum depends on fluctuation frequency as v-?-> * 9-2. These results are used to predict range change as a function of time scale and sun-earth-probe angle. Changes of interest for advanced navigation techniques are found to be likely.
