Abstract

um método e aparelho para operar um ou mais satélites em uma constelação de satélites em órbita não geossincronizada (ngso) são descritos. em alguns aspectos, uma área de cobertura na terra para um primeiro feixe transmitido a partir de um primeiro satélite na constelação de satélites ngso pode ser determinada, um cone pode ser projetado em uma primeira região da área de cobertura de feixe, uma segunda região da área de cobertura de feixe pode ser definida como incluindo partes da área de cobertura de feixe que se encontram fora da primeira região, e um ângulo mínimo de arco para cada um dentre uma pluralidade de pontos dentro da primeira região, mas não a segunda região da área de cobertura de feixe pode ser determinada.
