Abstract

The downlink signal from spacecraft in solar conjunction phases suffers a drastic reduction in signal-to-noise ratio (SNR). Responsible in large part for this effect is the increase in system noise temperature (SNT) in the ground antenna-receiver system. This article presents an empirical model of SNR degradation due to increasing SNT during solar conjunction phases.
