Abstract :
This talk highlights often-overlooked or poorly treated aspects in G/T error analyses for satellite communication earth terminals. In particular, correction factors due to star size, differential system temperature, antenna pointing, and refractive attenuation used in G/T measurements are discussed in detail.
