Title: Testing the Susceptibility of GNSS Receivers to Radio Frequency Interference
Authors: Henry Berglund, Frederick Blume, Warren Gallaher
To better characterize GNSS receiver susceptibility to more general RF interference, we use a signal generator to provide a Continuous Wave (CW) noise source. We combine the CW noise with the incoming signal from the GNSS antenna before it enters the receiver. We vary the power and frequency of the generated CW noise. Changes in the recorded signal-to-noise measurements are then used to characterize each receivers susceptibility to a CW noise source.
