Abstract

SE DESCRIBE UN SISTEMA DE RADIOBUSQUEDA QUE INCLUYE UN ENLACE DE SATELITE (40) PARA CONJUNTAR INFORMACION DE RADIOBUSQUEDA Y TRANSMITIRLO A UN SATELITE (26). EL SATELITE (26) PUEDE OPERAR PARA TRANSMITIR EN MODO MULTIPLE TODA LA INFORMACION A LOS DISTINTOS SISTEMAS REGIONALES DE RADIOBUSQUEDA (42). CADA UNO DE LOS SISTEMAS DE RADIOBUSQUEDA (42) INCLUYE UN NUMERO DE TORRES (10), CADA UNA DE LAS CUALES CONTIENE UN RECEPTOR SATELITE (50), UN DISCO DE SATELITE (48) ASOCIADO CON UN TRANSMISOR DE RADIOBUSQUEDA (52). CADA UNO DE LOS RECEPTORES SATELITES (50) SON OPERABLES PARA RECIBIR LA INFORMACION TRANSMITIDA DESDE EL SATELITE (26) AL MISMO TIEMPO, DE TAL MANERA QUE NO EXISTA DIFERENCIA DE FASE ENTRE NINGUNA DE LAS TORRES, INDEPENDIENTEMENTE DE SU LOCALIZACION. DE ESTA MANERA, LOS TRANSMISORES PUEDEN TRANSMITIR INFORMACION MEDIANTE ANTENAS (12) A LA FRECUENCIA DE RADIOBUSQUEDA, SIN CASI RETRASOS CON RELACION A CADA ANTENA (12). UN RECEPTOR ENLACE DE APOYO (28) ESTA DISPUESTO PARA INTERFASEAR CONEL TRANSMISOR DE ENLACE DE APOYO (70). EN EL CASO DE FALLO EN LOS RECEPTORES O EN EL SATELITE (26), EL TRANSMISOR DE ENLACE (70) TRANSMITIRA LA INFORMACION DE RADIOBUSQUEDA DIRECTAMENTE A LAS TORRES SELECCIONADAS, (10) EN FRECUENCIAS SEPARADAS.
