Abstract

La presente invención se refiere a un sistema para reutilizar el espectro de comunicaciones asignado a GEO en un sistema de comunicaciones basado en la constelación de satélites LEO, de manera que las señales originadas de satélites LEO no aparecerán en la anchura de haz de las antenas de estaciones terrestres apuntadas a GEO y satélites configurados para proporcionar comunicaciones manipulando sus respectivas transmisiones de haz, que pueden incluir un haz hacia delante y haz hacia atrás cuyos ángulos se controlan para proyectar el haz y reducir o eliminar la posibilidad de interferencia con las antenas de estaciones terrestres apuntadas a GEO. El sistema y satélites LEO pueden proporcionar una cobertura sustancialmente de 100% de una estación terrestre ubicada en cualquier lugar de la superficie de la tierra, sin coordinación con los satélites GEO o estaciones terrestres que apuntan a GEO. El sistema también puede proporcionar estaciones terrestres que son configuradas para mejorar el aislamiento entre el sistema de comunicaciones GEO y el sistema de comunicaciones LEO usando el mismo espectro para reducir el potencial que las antenas de estación terrestre apuntadas a GEO recojan la comunicación LEO.
