Abstract

This paper describes the recent results of a study aimed at accurately determining the antenna noise temperature used to calculate uplink G/T for satellite-borne receivers. The antenna noise temperature is calculated from a brightness temperature database of the Earth which, for each surface pixel (I deg x 1 deg). includes the effects of season, observation angle and frequency. Good correlation has been found by comparison with In-Orbit Test (IOT) measurements
