000188309 520__ $$aWith the availability in the years to come of several new Global Navigation Satellite Systems transmitting signals located in different frequency bands, the question of the feasibility of multi-frequency receivers aimed at the mass market is of major interest. Most solutions proposed today either use single-frequency receivers in parallel or directly sample the signals at the antenna, two solutions which are not applicable to the mass market. In this paper, a dual-frequency RF front-end architecture with a similar power-consumption and complexity as current state-of-the-art single-frequency front-ends is proposed. It is based on a super-heterodyne architecture and exploits the fact that the L1C/A and L2C signals only occupy 2 MHz of the 20 MHz L1 and L2 bands to allow the simultaneous acquisition and tracking of both the L1C/A and L2C signals.
