Abstract
The receiver includes: a correlation stage (7) formed of several correlation channels (7′) for receiving intermediate signals (IF) in order to correlate them, in operating channel control loops, with the carrier frequency and specific code replicas of visible emitting satellites to be searched and tracked, each channel having a correlator (8) in which at least one integrator counter (28, 29, 30, 31) provides, at the end of each determined integration period of the correlated signals, a binary output word whose value allows detection of the presence or absence of the visible satellite to be searched and tracked; and a microprocessor for processing the data drawn, after correlation, from the radio-frequency signals. The microprocessor configures at least one unused channel placed in parallel with one of the operating channels for searching and/or tracking the same visible satellite, the unused channel being configured so that the integration period of its integrator counter is different from that of the integrator counter of the operating channel.
