Abstract: PURPOSE: A receiver intended for the reception of pseudo-noise signals from the satellite radio-navigation systems is provided to reduce a code tracking error by multipath distortion and to generate a clock frequency and a heterodyne frequency signal with less frequency mixer. CONSTITUTION: A receiver for pseudo-noise signals from satellite radio-navigation systems uses the GLONASS and GPS systems. The signal outputs and the clock output of a radio-frequency converter(2) are connected respectively to the first and second signal and clock inputs of a N-channel digital correlation unit. A mixer is provided in each channel of a second signal-frequency converter in the radio-frequency converter. The output of said mixer is connected to the channel output through an amplifier with an adjustable amplification ratio and through a threshold device which are connected in series. The reference input of the second-channel mixer in the second signal-frequency converter is connected to the output of a signal with a second heterodyne frequency in an apparatus for generating clock- and heterodyne-frequency signals. A first and a second frequency splitting units are further connected in series to the apparatus. The receiver is characterized by its reduced dimensions and in that it does not include any complex elements such as a sampling circuit.
