Abstract: The method of determining the position of a radio-frequency signal receiver consists first of all in dividing the Earth's surface into N geographical regions as a function of the N channels available in the correlation stage of the receiver. At least one satellite in projection onto the Earth's surface has to be located in each of the N defined regions. The N channels of the correlation stage are each configured and switched on to search for a visible satellite in one of the N respective regions. Radio-frequency signal reception and shaping means pick up said radio-frequency signals and frequency convert them to provide intermediate signals to the correlation stage. Once one of the channels has detected a visible satellite in one of the N regions, the operation of all the other channels is interrupted by a stop block located in each of the other channels.

A second pass-band filter filters the signals from the first mixer unit, and provides signals to a second mixer unit to mix them with the second high frequency signals. Finally, shaping means for the signals provided by the second mixer unit generate the intermediate signals.
