Abstract: The invention relates to a receiver of a system for positioning by satellite, including: a channel filter (SAW) in which a signal transmitted by satellite and received by the receiver is propagated along a direct path and indirect paths in an odd order; upstream from the channel filter, a tracking loop being controlled by means of a control correlator (C1), the receiver being characterized in that it comprises: an offset register (RD) configured to generate a plurality of local replicas (S5) of said code, which are offset from one another such as to cover a time window corresponding to twice the uncertainty on an estimate of a propagation time when passing directly through the channel filter, a second correlator (C2) offset relative to the control correlator by a time corresponding to twice said propagation time estimate when passing directly through the channel fitter, said second correlator being configured to correlate the code for spreading the signal transmitted by the satellite with said local replicas

Abstract: A method and receiver for reducing a signal (B) interfering with a broadband spread-spectrum signal (A) reaching a receiver (100), the receiver (100) including an interference signal (B) reduction system (20) incorporating an automatic gain controller (21), said method characterized in that the controller (21) continuously carries out a normalization (B?) of an instantaneous peak amplitude of the signal (B), wherein said instantaneous peak amplitude is constant in time for the signal thus normalized (B?).
