Abstract

UN METODO Y APARATO PARA DETERMINAR LA LOCALIZACION DE UNA UNIDAD MOVIL (412) EN UN SISTEMA CELULAR. UNA SEÑAL SINCRONIZADA EN UNA FASE COMUN SE GENERA EN CADA ESTACION BASE (400, 401, 402) EN UN SISTEMA. LA UNIDAD MOVIL (412) TRANSMITE UN TONO DE SEÑAL. CADA ESTACION BASE (400, 401, 402) COMPARA LA FASE DEL TONO DE SEÑAL CON LA FASE COMUN DE LA SEÑAL SINCRONIZADA PARA PRODUCIR UN DESVIO DE FASE. UN CONTROLADOR DEL SISTEMA COMPARA LA DIFERENCIA ENTRE EL DESVIO DE FASE DE UNA PRIMERA ESTACION BASE (400) Y EL DESVIO DE FASE DE UNA SEGUNDA ESTACION BASE (401) Y DETERMINA LA DIFERENCIA DE DISTANCIA ENTRE LA PRIMERA ESTACION BASE (400) Y LA UNIDAD MOVIL (412) Y LA SEGUNDA ESTACION BASE (401) Y LA UNIDAD MOVIL (412) QUE DEFINE UNA CURVA HIPERBOLICA O LINEAL DE LOCALIZACIONES. EL CONTROLADOR DEL SISTEMA COMPARA LA DIFERENCIA ENTRE EL DESVIO DE FASE DE LA PRIMERA ESTACION BASE (400) Y EL DESVIO DE FASE DE UNA TERCERA ESTACION BASE (402) Y DETERMINA LA DIFERENCIA DE DISTANCIA ENTRE LA PRIMERA ESTACION BASE (400) Y LA UNIDAD MOVIL (412) Y LA TERCERA ESTACION BASE (402) Y LA UNIDAD MOVIL (412) QUE DEFINE UNA SEGUNDA CURVA HIPERBOLICA DE LOCALIZACIONES. EL CONTROLADOR DEL SISTEMA DETERMINA LA INTERSECCION DE LA PRIMERA Y SEGUNDA CURVAS HIPERBOLICAS DETERMINANDO ASI LA LOCALIZACION DE LA UNIDAD MOVIL (412).
