HIGH-SENSITIVITY SIGNAL RECEIVER OF GLOBAL NAVIGATION SATELLITE SYSTEMS Russian patent published in 2018 - IPC G01S19/13 

FIELD: radio engineering; electronics.

SUBSTANCE: invention relates to radio engineering, namely to the field of radio navigation, and can be used in the construction of receivers of Global Navigation Satellite Systems (GNSS). This result is achieved due to the fact that the receiver consists of a series-connected antenna unit, signal multiplexing unit, analog radio frequency converter, digital frequency converter, packet signal memory, packet tuner, correlation unit and frequency analysis block, as well as reference oscillator whose output is connected to the input of the reference frequency of the RF transducer; accumulation memory unit whose input is connected to the output of the correlation unit and the input and output of the frequency analysis block; processor with memory and interface units, the input / output of which is connected to the input / output of the correlation unit, frequency analysis block, and accumulation memory block by a digital data bus; wherein the second input of the correlation unit is connected to the second output of the packet memory of the signals via the demultiplexing code generator; and the third output of the packet memory of the signals is connected to the second input of the signal multiplexer; and the second processor input / output is the external information input / output of the receiver.

EFFECT: achieved technical result is the increase of sensitivity, accuracy and noise immunity of the multisystem GNSS receiver.
