Abstract: Un procedimiento que comprende: recibir, en un receptor (300), una señal compuesta que incluye una señal de una primera señal de un sistema de localización por satélite (SPS) en una primera frecuencia portadora (f1), transmitida desde un primer sistema global de navegación por satélite (GNSS1) y una segunda señal del SPS en una segunda frecuencia portadora (f2), transmitida desde un segundo sistema global de navegación por satélite (GNSS2), siendo la primera frecuencia portadora (f1) diferente a la segunda frecuencia portadora (f 2); procesar la señal compuesta que incluye la primera señal del SPS y la segunda señal del SPS en una única trayectoria receptora que comprende una única serie de componentes receptores para procesar de forma simultánea la primera señal del SPS y la segunda señal del SPS en la señal compuesta, comprendiendo la única serie de componentes receptores una antena (302) de frecuencia de radio (RF), un filtro de RF de paso de banda (304) y un amplificador de poco ruido (306); reducir la frecuencia de la señal compuesta que incluye la primera señal del SPS y la segunda señal del SPS en una única etapa de reducción de frecuencia compleja para mezclar la señal compuesta, que incluye la primera señal del SPS y la segunda señal del SPS, con una señal de oscilador local en una frecuencia de oscilador local, para producir señales compuestas en una única frecuencia intermedia, comprendiendo las señales compuestas componentes en fase (I) y en cuadratura (Q); muestrear de forma digital las señales compuestas en la única frecuencia intermedia para proporcionar componentes muestreados en fase (I) y en cuadratura (Q); aplicar la reducción de frecuencia de la segunda etapa a los componentes muestreados en fase (I) y en cuadratura (Q) para proporcionar muestras de salida para el procesamiento de banda base de acuerdo al primer Sistema Global de Navegación por Satélite (GNSS1) y muestras de salida para el procesamiento de banda base de acuerdo al segundo Sistema Global de Navegación por satélite (GNSS2); y obtener, en base a las muestras de salida de la reducción de frecuencia de la segunda etapa, una medición de seudo-distancia para cada una de las señales primera y segunda del SPS con frecuencia reducida.

Abstract: Methods and apparatuses for processing Satellite Positioning System (SPS) signals. In one exemplary method, a first set of frequency coefficient, whic h corresponds to a first Doppler frequency of an SPS signal, is determined, an d said SPS signal is processed in a matched filter with the first set of frequency coefficients during a first window of time. A second set of frequency coefficients, which corresponds to a second Doppler frequency of t he SPS signal, is determined, and the SPS signal is processed in the matched filter with the second set of frequency coefficients during a second window of time, where the first and second windows of time occur within a period of ti me which is not greater than one SPS frame period. In another exemplary method, a first SPS signal is processed in a matched filter with a first set of pseudonoise (PN) coefficients during a first window of time, where the first set of PN coefficients corresponds to the first SPS signal, and a second SPS signal is processed in the matched filter with a second set of PN coefficien ts (which correspond with the second SPS signal) during a second window of time , wherein the first window and the second windows occur within a period of tim e not greater than one SPS frame period.
