Abstract

LA INVENCION SE REFIERE A UN RECEPTOR DE BANDA ANCHA PARA LA MEDICION DE DISTANCIA POR SEÑALES DE CODIGO SEUDOALEATORIO. ESTE CODIGO LLEVA UN TRATAMIENTO DE SEÑAL QUE UTILIZA LA CORRELACION DE LA SEÑAL COMPUESTA RECIBIDA CON CODIGOS SEUDOALEATORIO GENERADOS LOCALMENTE, AVANZADOS/RETARDADO. EL GENERADOR DE CODIGO (580) ENVIA SUS SEÑALES A UNA LINEA DE RETARDO (582) CUYAS SALIDAS REGULARMENTE ESPACIADAS (E2, E1, P, P1) ESTAN COMBINADAS SEGUN LA RELACION C=E2 - 2E + 2L1 - L2 ANTES DE SER ENVIADAS A UN CORRELACIONADOR (C2), MIENTRAS QUE EL OTRO (C1) RECIBE LA SEÑAL PUNTUAL (P). ESTO REDUCE NOTABLEMENTE EL ERROR DE POSICION DEBIDO A LOS RETARDOS DE TRAYECTO MULTIPLE. LA INVENCION SE APLICA PARTICULARMENTE EN LOS RECEPTORES DE LOS SISTEMAS GPS O GLONASS.
