Patent ID: 7092433

Claim:
A receiver for radio-frequency signals transmitted by transmitting sources, in particular of the GPS type, said receiver including: receiving and shaping means with frequency conversion for the radio-frequency signals for generating intermediate signals, a correlation stage formed of several correlation channels for receiving the intermediate signals in order to correlate them, in control loops of operating channels, with carrier frequency replicas and specific code replicas of visible transmitting sources to be searched and tracked, each channel being provided with a correlator in which at least one integrator counter is capable of providing, at the end of each determined integration period of the correlated signals, a binary output word whose value, compared to a determined detection threshold level, allows detection of the presence or absence of the transmitting source to be searched and tracked, and microprocessor means connected to the correlation stage for processing data extracted, after correlation, from the radio-frequency signals, wherein the microprocessor means is arranged to configure at least one unused channel placed in parallel with one of the operating channels for searching and/or tracking a same visible transmitting source, the unused channel being configured so that the integration period of its integrator counter is different from the integration period of the integrator counter of the operating channel.
