Abstract
IThis paper focuses on interference aspects related to non-GSa satellite systems and presents results reflecting the effect of the oscillatory shape of the earth station antenna sidelobe gain pattern in the statistical behaviour of the aggregate interference produced by an interfering non-GSa system into the satellites of an interfered-with system. A Bessel function type of radiation pattern was adopted as a more realistic model for the antenna sidelobe gain since it reflects the oscillatory behaviour encountered in measured radiation patterns. This sidelobe gain oscillatory behaviour plays an important role when addressing interference calculations involving non-GSa systems, since due to the non-GSa system satellites dynamics not all entries in the aggregate interference are associated with the maximum sidelobe earth station antenna gain. Results indicate that. although often used in GSa satellite systems. this type of worst case interference calculation tends to be overly pessimistic if applied to the non-GSa satellite environment.
