Abstract

PARA REDUCIR EN UN SISTEMA GPS DIFERENCIAL LA NECESIDAD DE CAPACIDAD DE TRANSFERENCIA PARA LOS DATOS DE CORRECCION, MEJORAR NOTABLEMENTE LA CAPACIDAD DE VALORACION DE LOS DATOS DE CORRECCION EN EL CASO DE FALLOS DE TRANSFERENCIA, ASI COMO AUMENTAR LA ACTUALIDAD DE LOS DATOS DE CORRECCION A TRANSFERIR, A PARTIR DE LAS SEÑALES GPS (12, 22, 32, 42) RECIBIDAS CONSTANTEMENTE POR UN RECEPTOR GPS DE REFERENCIA (50) Y DE LAS COORDENADAS DE POSICION CONOCIDAS DE SU EMPLAZAMIENTO (6) SE DETERMINAN UNOS VALORES DE ERROR CONTINUOS Y DE AQUI SE CONFIGURAN UNOS VALORES DE CORRECCION (7). CONFORME A LA INVENCION SE HA PREVISTO UN DISPOSITIVO DE VALORACION (60), QUE RECALCULA LOS VALORES DE CORRECCION CALCULADOS EN UN MOMENTO DETERMINADO EN EL MOMENTO DEL ULTIMO MINUTO COMPLETO. LOS VALORES DE CORRECCION (8) TRATADOS POR EL DISPOSITIVO DE VALORACION SE EMITEN DESDE AL MENOS UN EMISOR DE RADIODIFUSION (80) COMO DATOS DE UNA SEÑAL DE DATOS DE RADIODIFUSION (RDS-SIGNALS) INSERTADOS EN SU SEÑAL DE PROGRAMA. ENEL OBJETO MOVIL (5), CUYAS COORDENADAS DE POSICION SE DETERMINAN MEDIANTE UN RECEPTOR GPS MOVIL (120), SE DISPONE DE UN RECEPTOR DE RADIODIFUSION (90), AL QUE SE HAN POSCONECTADO UN DECODIFICADOR RDS (100) PARA RECIBIR Y DECODIFICAR LA SEÑAL RDS DOTADA DE LOS VALORES DE CORRECCION TRATADOS (8), ASI COMO UN ORDENADOR (110) QUE SEPARA LOS VALORES DE CORRECCION (7) DE LA SEÑAL RDS DECODIFICADA Y ACTUALIZA EL TIEMPO MOMENTANEO. APARTE DE ESTO, EL ORDENADOR RECONSTRUYE UNA SEÑAL DE CORRECCION NORMALIZADA (7) SEGUN LA NORMATIVA RTCM. LOS DATOS DE CORRECCION RECONSTRUIDOS NORMALIZADOS SE ALIMENTAN AL RECEPTOR GPS MOVIL, QUE CORRIGE SUS RESULTADOS DE MEDICION SEGUN LOS VALORES DE CORRECCION RECONSTRUIDOS (7).
