Abstract

Un sistema de comunicaciones por satélite que incluye por lo menos una repetidora de señal de comunicacion por satélite; por lo menos una estacion terrestre para transmitir un enlace de alimentador compuesto de una pluralidad de señales de comunicacion a por lo menos una repetidora de señal de comunicaciones por satélite, y una pluralidad de terminales de usuario cada una recibiendo una de las señales de comunicacion sobre un enlace de usuario desde una repetidora de señal de comunicacion por satélite; el sistema de comunicacion por satélite incluye además un sistema de control de potencia de circuito cerrado que tiene una pluralidad de circuitos internos, circuitos individuales que operan para compensar un de los enlaces de usuario para alteraciones de señal de comunicaciones que ocurren por lo menos entre la terminal de usuario y la repetidora de comunicaciones de satélite, y un circuito exterior que opera para compensar todos los enlaces de usuario para alteraciones de enlace de alimentador que ocurren entre por lo menos una estacion terrestre y por lo menos una repetidora de señal de comunicaciones por satélite.
