Abstract: The invention relates to a method for acquisition of a signal (2) emitted by a satellite, by a receiver in a satellite Positioning System using a multi-code correlation and a multi-frequency correlation, also comprising the step in which if the error induced at the output from a first frequency-augmented correlator (14) at each instant in an integration period is greater than the code space between code correlators (12), the summated results of the first frequency-augmented correlator (14) are transferred to the summated results of a second frequency-augmented correlator (14), the second frequency-augmented correlator (14) using the same frequency-shift as the first frequency-augmented correlator (14) and being associated with a second code correlator (12) that is shifted by the code space from the first code correlator (12) with which said first frequency-augmented correlator (14) is associated.

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?).
