Abstract

sistema para reutilização de espectro de comunicações alocado por geo em um sistema de comunicações baseado em constelação de satélites de leo, de modo que o sinais originados por satélite de leo não apareçam na largura de feixe de antenas de estação terrestre apontadas para geo, e satélites configurados para fornecer comunicações manipulando-se suas respectivas transmissões de feixe, que podem incluir um feixe para frente e feixe para trás cujos ângulos são controlados para projetar o feixe e reduzir ou eliminar o potencial para interferência com antenas de estação terrestre apontadas para geo. o sistema e satélites de leo podem fornecer substancialmente 100% de cobertura de uma estação terrestre localizada em qualquer ponto na superfície da terra, sem coordenação com os satélites de geo ou estações terrestres de apontamento para geo. o sistema também pode fornecer estações terrestres que são configuradas para acentuar o isolamento entre o sistema de comunicações de geo e o sistema de comunicações de leo com o uso do mesmo espectro para reduzir o potencial para antenas de estação terrestre apontadas para geo de captar a comunicação de leo.
