Abstract

Las realizaciones proporcionan una configuración en vuelo de las vías de transmisión de satélites para dar servicio de manera flexible al tráfico de enlaces terrestres y enlaces cruzados en una constelación de satélites no procesados, por ejemplo, para facilitar una capacidad flexible del canal de envío y el canal de retorno en un sistema de comunicaciones por satélite. Por ejemplo, cada satélite en la constelación puede incluir una o más vías de transmisión configurables de manera dinámica, y se puede utilizar la conmutación y/o la conformación de haces para configurar que cada vía de transmisión sea una vía de transmisión de un canal de envío o una vía de transmisión de un canal de retorno, en cada uno de varios intervalos de tiempo, de acuerdo con un plan de configuración de las vías de transmisión. Al menos algunas de las vías de transmisión se pueden configurar adicionalmente de manera selectiva, en cada intervalo de tiempo, de modo que transporten tráfico de “enlace terrestre” a, y/o desde, terminales terrestres, y tráfico de “enlace cruzado” a, y/o desde, uno o más satélites diferentes de la constelación.
