Abstract

The invention relates to a front-end architecture (1,1 ') for receiving simultaneously a first and a second satellite signal of a satellite positioning system as well as to a related method, said architecture comprising: conversion means for converting a radiofrequency signal into an intermediate-frequency signal, wherein the conversion means (3) comprise a fixed- frequency local oscillator (31), and extraction means (23,28) for extracting the first and second satellite signal from the intermediate-frequency signal, wherein the extraction means (23,28) can be operated at a sampling rate which is a function of an oscillation frequency generated by the local oscillator (31) and which allows undersampling of the intermediate-frequency signal.
