Abstract

LA INVENCION DESCRIBE UN SISTEMA PARA LA GENERACION DE SEÑALES DE RADIO DIGITALES PARA UNA TRANSMISION DE SATELITE CON MULTIPLES ESTACIONES DESCENTRALIZADAS EN EL SUELO COMO FUENTES DE SEÑALES DE RADIO Y UN TRANSPONDER DE SATELITE. LA TRANSMISION DE SEÑALES DE RADIO DIGITALES DERIVADAS DE LAS ESTACIONES DEL SUELO SE CONSIGUE DE FORMA DESCENTRALIZADA EN DISPOSICION MULTIPLEX DE TIEMPO CON RESPECTO AL TRANSPONDER DEL SATELITE. PARA LA SINCRONIZACION DE LAS ESTACIONES DEL SUELO SE UTILIZA UNA BASE DE TIEMPO CONJUNTA PRECISA, DONDE SE TRATA CON PREFERENCIA DE UNA SEÑAL DE REFERENCIA DE TIEMPO RADIADA POR EL SATELITE DE UN SISTEMA DE NAVEGACION Y/O LOCALIZACION.
