摘要
A system for receiving a radionavigation signal, notably in a jammed medium, emitted by a satellite of a satellite positioning system, includes: at least one first multi-correlator and at least one second multi-correlator disposed in parallel and operating respectively at a frequency; filtering means, disposed upstream of said multi-correlators; a delay line, disposed on the branch, between the filtering means and the second multi-correlator; means for sub-sampling at the frequency adapted for sub-sampling the signal transmitted directly and by branching with delay by the filtering means; and demodulation means eliminating the Doppler effect, disposed between the sub-sampling means and the first and second multi-correlators.
