The ITU Radiocommunication Assembly considering a) that environmental and other effects are important factors in determining the end of life performance of a satellite antenna; b) that satellite antenna side-lobe levels can vary due to environmental factors, operational factors and ageing; c) that satellite antenna radiation pattern is an important parameter in the interference calculations; d) that the use of active array antennas in the operational satellite environment is increasing; e) that methods to assess the environmental effects on the performance of a satellite antenna depend on the technologies used for the antenna; f) that for some systems, the primary source of interference into an earth station is from the satellite antenna side lobes into the earth station.
