Abstract

Una ruta de comunicación por radio permite la comunicación de una estación terrestre de origen a una estación terrestre de destino a través de uno de los múltiples satélites que giran al azar en órbita sin control de actitud activo. Las estaciones terrestres y los satélites incluyen antenas direccionales para recibir señales de radio y transmitir señales de radio en múltiples direcciones. Los satélites almacenan una dirección de una estación terrestre de destino desde la cual se transmite una señal de información inicial y la información de la antena identifica la antena satelital en la que se recibió la señal de información inicial. Las múltiples antenas satelitales transmiten información de enlace que identifica el satélite a la estación terrestre de origen. Las transmisiones de datos recibidas en la estación terrestre de origen que designan un destino particular son transmitidas por la estación terrestre de origen usando la antena en la que se recibió la información de enlace y el satélite retransmite la transmisión de datos usando la antena satelital identificada por la información de antena almacenada.
