Abstract
SISTEMA DE COMUNICACIONES MOVILES POR SATELITE. CARACTERIZADO PORQUE LAS COMUNICACIONES EN EL SENTIDO MOVIL-SATELITE SE REALIZAN UTILIZANDO LOS CANALES DE BUSQUEDA Y SALVAMENTO DE LOS SATELITES MARECS; PORQUE LAS COMUNICACIONES EN EL SENTIDO SATELITE-MOVIL SE REALIZAN MEDIANTE LA CONCENTRACION, EN UN SOLO CANAL, DE TANTOS CANALES MARECS COMO SE REQUIERAN PARA OBTENER LA VELOCIDAD DE TRANSMISION DE INFORMACION DESEADA; PORQUE LA RELACION DE GANANCIA A TEMPERATURA DE RUIDO DE ANTENA, DE LOS EQUIPOS TERMINALES MOVILES, SE ENCUENTRA EN LA GAMA DE VALORES COMPRENDIDA ENTRE -28 DB/ K Y -22 DB/ K; Y PORQUE LA POTENCIA ISOTROPICA RADIADA EQUIVALENTE, DE LOS EQUIPOS TERMINALES MOVILES, SE ENCUENTRAN EN LA GAMA DE VALORES COMPRENDIDA ENTRE 12 DBW Y 18 DBW.
