Calculation of interference from fixed services to a deep space earth station

This paper aims at methodology of calculation of interference from terrestrial services to a deep-space earth station. Certain radiowave propagation issues related to calculation of the interference are addressed. The purpose of the analysis is to determine the possible level of interference in 32 GHz frequency band with respect to the reliability of operation of deep space missions. The methodology is applied to Robledo deep space earth station, Spain. The results are given in form of statistical distribution of interference levels.
