GNSS receivers are vulnerable to radio frequency interference. One can use signal processing techniques to suppress interference. However, the signal processing techniques are limited to narrowband interfering signals. Spatial processing using adaptive antenna, therefore, has become the universal choice for suppression of radio frequency interference in GNSS receivers. We will discuss how the various antenna parameters and weighting algorithms affect C/No and antenna induced biases in GNSS receiver measurements.
