Abstract

SE EMPLEA UN PAR DE ANTENAS (230A, 230B) EN COMBINACION CON UN SISTEMA DE RECEPTORES DE SEÑALES GPS, PARA DETECTAR LA RECEPCION DE SEÑALES DE INFORMACION DE SATELITE A PARTIR DE UN TRANSMISOR DE SEÑALES DE INTERFERENCIA EN OPOSICION A DICHAS SEÑALES DE INFORMACION DEL SATELITE, TRANSMITIDAS A BORDE DE CADA UNO DE LOS SATELITES, QUE FORMAN UN SISTEMA DE POSICIONAMIENTO POR SATELITE. SE DETECTA LA INDICACION DEL ANGULO DE APUNTAMIENTO ( AL ) O ( BE ) ENTRE LA LINEA DE LAS ANTENAS Y EL EMISOR EN CURSO EMITIENDO LAS SEÑALES DE INFORMACION DEL SATELITE. EL ANGULO DE APUNTAMIENTO Y/O ALTERNATIVAMENTE LA DIFERENCIA DE DISTANCIA DERIVADA DE LAS SALIDAS DE LOS RESPECTIVOS SISTEMAS (240A, 240B), PUEDEN OBSERVARSE MEDIANTE LA MONITORIZACION DEL COMPORTAMIENTO DEL CODIGO PSEUDOALEATORIO ASOCIADO CON LA PORTADORA DE LA SEÑAL DE INFORMACION DEL SATELITE, O LA PROPIA PORTADORA EN SI. A SU VEZ, LAS MEDIDAS DE PSEUDODISTANCIAS, MEDIDAS DE PSEUDOVARIACIONES DE DISTANCIAS, MEDIAS DE FASE DE PORTADORAS, Y/O LAMEDIDA DE COMPUTO DOPPLER ASOCIADAS CON LAS DOS ANTENAS PUEDEN SER UTILIZADAS PARA OBTENER LA DISCRIMINACION DESEADA, QUE DISTINGUE ENTRE LAS SEÑALES GENUINAS DEL SATELITE, Y AQUELLAS QUE SON REDADIADAS VIA LA ANTENA TERRRENA DEL TRANSMISOR DE SEÑALES DE INTERFERENCIA.
