DEVICE FOR DETECTION OF GNCS UNE SPURIOUS NAVIGATION SIGNALS SOURCES Russian patent published in 2019 - IPC G01C21/24 

FIELD: navigation.

SUBSTANCE: invention relates to the field of identifying the sources of spurious navigation signals of user navigation equipment (UNE) of the global navigation communication system (GNCS). Device consists of an antenna array containing antenna elements, blocks of weight coefficients of the chart-forming circuit, adder, device for implementing the control algorithm, direction finder, navigation signal receiver, informational message analyzer. Outputs of the antenna elements of the antenna array are connected to the corresponding inputs of the direction finder and the inputs of the weighting units of the chart-forming circuit. Output of the direction finder is connected to the input of the navigation message analyzer, which has an output connected to the input of the device implementing the control algorithm. Outputs of the blocks of weights of the diagram-forming circuit are connected to the corresponding inputs of the adder, the output of which is connected to the input of the receiver of navigation signals. Outputs of the receiver are connected to the corresponding inputs of the analyzer information messages.

EFFECT: technical result consists in the possibility of detecting sources of spurious navigation signals of the GNCS UNE in the stream of received radio signals by an adaptive antenna array.
