Abstract
SE REVELA AQUI UN METODO Y APARATO PARA SINTETIZAR UNA SEÑAL DE REFERENCIA ESTABLE DE UNA FRECUENCIA DESEADA DENTRO DE UN RECEPTOR DE ESPECTRO DE PRECISION.EL RECEPTOR DE ESPECTRO DE PRECISION ESTA DISEÑADO PARA USARLO EN CONJUNCION CON UN RECEPTOR DE SISTEMA DE POSICIONAMIENTO GLOBAL (GPS), Y OPERA PARA RECIBIR INFORMACION DE CORRECCION DIFERENCIAL DE DIFUSION GPS. LA PRESENTE TECNICA DE SINTESIS DE FRECUENCIA CONTEMPLA GENERAR UNA SECUENCIA DE SEÑALES DE SINCRONIZACION DENTRO DEL RECEPTOR GPS EN LA BASE DE LAS SEÑALES DE SATELITE GPS RECIBIDAS DE ESE MODO, Y PROPORCIONAR LAS SEÑALES DE SINCRONIZACION AL RECEPTOR DE SEÑALES. DENTRO DEL RECEPTOR DE SEÑAL, LOS CICLOS DE SEÑAL DE UN OSCILADOR LOCAL QUE OCURRE ENTRE UNAS DE LAS SEÑALES DE SINCRONIZACION ESTAN CONSIDERADAS. LA FRECUENCIA DEL OSCILADOR LOCAL SE DETERMINA ENTONCES POR DIVIDIR LOS CICLOS CONSIDERADOS DEL OSCILADOR LOCAL POR UNO DE LOS INTERVALOS DE TIEMPO CONOCIDOS. LAS FRECUENCIAS DETERMINADAS DE LAS SEÑALES DE SALIDA PRODUCIDA POR EL OSCILADOR LOCAL ENTONCES SE GRADUA PARA PRODUCIR LA SEÑAL DE REFERENCIA DE FRECUENCIA DESEADA. ESTO PERMITE FRECUENCIAS DE REFERENCIA REGULADAS CON PRECISION PARA SER OBTENIDAS INDEPENDIENTEMENTE DE LA EXISTENCIA DE INESTABILIDAD DE FRECUENCIA DENTRO DEL OSCILADOR LOCAL. EN UNA IMPLEMENTACION NORMALIZADA, LAS SEÑALES DE REFERENCIA ESTABLES SE EMPLEAN DURANTE LA ADQUISICION DE SEÑALES DE CORRECION GPS DIFERENCIALES RECIBIDAS POR EL RECEPTOR DE ESPECTRO DE DISPERSION. EN PARTICULAR, LA FRECUENCIA DE REFERENCIA DESEADA SE AJUSTA INCREMENTALMENTE DURANT EL PROCESO DE BUSQUEDA Y ADQUIERE LA FRECUENCIA EXACTA DE LAS SEÑALES DE CORRECION GPS DIFERENCIAL CASUALES. EL RECEPTOR DE ESPECTRO DE DISPERSION ESTA DISPUESTO PARA PROPORCIONAR INFORMACION DE CORRECION GPS DIFERENCIAL EXTRAIDA DE LAS SEÑALES DE CORRECCION ADQUIRIDAS PARA EL RECEPTOR GPS.
