    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.

    Abstract: PURPOSE: A code generator is provided to minimize the number of components in an equipment used and simplify the structure by using the common elements of the generator for generating both codes. CONSTITUTION: A receiving signal of the GPS and GLONASS SRNS(Satellite Radio-Navigation Systems) is converted a frequency, modulated, and is processed the digital correlation. A generator for generating a code of pseudo-random sequences is used as reference code generators during the digital correlation processing of signals in multi-channel receivers for receiving pseudo-noise signals. The generator for the SNRS operates in two modes, i.e. a mode for generating a code of pseudo-random sequences for the GPS system and a mode for generating a code of pseudo-random sequences for the GLONASS system. This result can be achieved by an optimization of the connection and interaction between the standard components of the generator.

    Abstract: PURPOSE: A digital correlator is provided to ensure a reliable frequency division of the signals from the GLONASS(GLObal NAvigational Satellite System) in receivers that receive pseudo-noise signals from the GPS and GLONASS and ensure the reception and the correlation processing of the signals C/A of the codes of the systems within a frequency range L1/F1. CONSTITUTION: A digital correlator of the SRNS signal receiver comprises N channels. The first and second signal inputs of the channels, the clock inputs and the inputs-outputs of all N channels are interconnected and form, respectively, a first and a second signal inputs, a clock input and an input-output of the digital correlator. The first and second signal inputs of the switchboard form first and second signal inputs of the channel respectively. The input-output of the unit form an input-output of the channel. The clock inputs of the storage units, generators and programmed delay lines are connected to each other and form a clock input of the channel.
