A Study of the Measurement of G/T Using Cassiopeia A

Abstract

The report describes a study intended to estimate the best possible accuracy of measuring the ratio G/T (System gain to system noise temperature) of a satellite communication ground station using the radio star Cassiopeia A (Cas A). The concept of G/T and its measurement using a radio star is briefly discussed. Results of an extensive literature search are presented, summarizing the properties of Cas A and its vicinity described by radio astronomers in order to utilize this information to assess the accuracy of a G/T measurement.
