Abstract
This article advances the hypothesis that observed doppler noise during solar conjunctions is proportional to total columnar electron content along the signal path. This assumption leads directly to a geometrical model (“ISED”) for observed doppler noise which is shown to be in very good agreement with doppler noise data accumulated during the 1975 Pioneer 10, Pioneer 11 and Helios 1 solar conjunctions. An augmented model (“RISED”) is constructed which quantitatively indicates correlation between Earth observed Sunspot activity and systematic, cyclical deviations from the ISED model. Applications expected from this effort are: (1) Ability to validate generation of doppler data during solar conjunctions, (2) Ability to predict solar corruption of doppler data during mission critical phases which occur during solar conjunctions, and (3) Possibility of extracting electron density information from observed doppler noise.
