Abstract

PARA DETERMINAR EL RETARDO DE EQUALIZACION DE UNA SUB-ESTACION (S3), LA ESTACION PRINCIPAL (C) DE UN SISTEMA DE TRANSMISION MIDE, DURANTE UNA MEDICION APROXIMADA INICIAL, EL INTERVALO DE TIEMPO ENTRE EL ENVIO DE UNA PRIMERA SEÑAL DE MEDICION DE DISTANCIAS A LA SUB-ESTACION Y LA RECEPCION DE UNA SEÑAL DE RESPUESTA. ESTA SEÑAL DE RESPUESTA TIENE UNA FRECUENCIA Y UNA AMPLITUD SUBSTANCIALMENTE INFERIORES A LAS SEÑALES DE INFORMACION ENVIADAS POR OTRAS SUBESTACIONES (S1, S2) DEL SISTEMA PARA EVITAR INTERFERENCIA CON LAS MISMAS. DURANTE UNA MEDICION PRECISA POSTERIOR, LA ESTACION PRINCIPAL MIDE EL INTERVALO DE TIEMPO ENTRE EL ENVIO DE UNA SEGUNDA SEÑAL DE MEDICION DE DISTANCIA Y LA RECEPCION DE UNA SEGUNDA SEÑAL DE RESPUESTA QUE TIENE LAS MISMAS CARACTERISTICAS QUE LAS SEÑALES DE INFORMACION. EL RESTO DE LAS SUBESTACIONES TIENEN QUE INTERRUMPIR LA TRANSMISION DE SEÑALES DURANTE UN INTERVALO IGUAL AL INTERVALO DE TIEMPO DE INCERTIDUMBRE CON EL QUE SE MIDIO EL RETARDO DE EQUALIZACION DURANTE LA MEDICION APROXIMADA. PARA PODER APLICAR ESTE METODO, EL RECEPTOR DE LA ESTACION PRINCIPAL INCLUYE MEDIOS PARA AISLAR (AZ) LA PRIMERA SEÑAL DE RESPUESTA A PARTIR DE LAS SEÑALES DE INFORMACION Y RECONOCERLAS (COR), Y UNA UNIDAD DE PROCESO (UP) DETERMINA EL RETARDO DE EQUALIZACION.
