Efeito de modificações nas áreas de cobertura das alocações brasileiras do Plano de Serviço de Radiodifusão por Satéline da UIT no ambiente interferente do Plano

The use of gestationary, allowed for a large development in long distance communications and broadcasting. Since the geostationary satellite orbit (GSO) is limited resource, there is motivation for a priori planning of the use of this resource so that access to the GSO is guaranteed to all countries. These a priori planning involve studies, analysis and modeling that depend of the specific characteristics of the systems being planned. Motivated by specific interests of the Brazilian administration, this work presents a precise analysis of the effect that changes in the technical parameters of the Brazilian allocations in the ITU Bradcasting Satellite Service Plan would have on the interferences generated and experienced by the systems in the Plan.
