Tracking and Mitigating a Jamming Signal with an Adaptive Notch Filter
The rise of inexpensive yet powerful GNSS jammers is driving numerous R&D efforts to find ways to thwart the use of such devices. Researchers at the European Commission Joint Research Center describe their use of an infinite impulse response adaptive notch filter to mitigate the effects of jamming.
