Abstract

TRANSMISION DE DATOS DE CORRECCION GPS MEDIANTE RDS EN LA RED COMERCIAL DE FM. CONSISTENTE EN UNA CADENA COMERCIAL DE ESTACIONES DE RADIO INSTALADAS EN UNAS POSICIONES GEOGRAFICAS CONOCIDAS, DOTADA CADA UNA DE ELLAS DE UN RECEPTOS GPS DIFERENCIAL CAPAZ DE CALCULAR LAS CORRECCIONES DE DISTANCIA Y VELOCIDAD DE LOS SATELITES VISIBLES Y DE TRANSMITIRLAS A LOS USUARIOS MEDIANTE EL RADIO DATA SYSTEM (RDS) DE LAS EMISORAS DE FRECUENCIA MODULADA (FM) COMERCIALES, EN UN FORMATO RTCM CON O SIN ENCRIPTACION. LOS USUARIOS DISPONEN DE UN RECEPTOR COMERCIAL DE FM RDS O DE UN RECEPTOR DEDICADO, DONDE UNA VEZ OBTENIDA LA BANDA BASE (11), SE DEMODULA (15) Y DECODIFICA (17) EL RDS PARA OBTENER LOS MENSAJES DE CORRECCIONES DGPS (18), QUE SON DESENCRIPTADOS Y CONFORMADOS (20) PARA SER UTILIZADOS POR CUALQUIER RECEPTOR DGPS (23) COMERCIAL. EL ENCRIPTADO Y DESENCRIPTADO SE BASA EN OPERACIONES LOGICAS Y DESDE LA EMISORA SE PUEDE INHIBIR LA RECEPCION DE CORRECCIONES A UN USUARIO O GRUPO DE ELLOS.
