Abstract
A global navigation satellite system (GNSS) receiver includes radio frequency front end and digital processing functionality. Radio frequency front end includes radio frequency input; first variable gain amplifier adjusts first gain of first frequency range of first analog GNSS signal received from radio frequency input by first amount; and second variable gain amplifier adjusts second gain of second frequency range of second analog global navigation satellite system signal received from radio frequency input by second amount. Digital processing functionality compares first amount of adjustment of first gain of first frequency range with second amount of adjustment of second gain of second frequency range; and detects first interference signal present in first frequency range or second frequency range when first amount of adjustment of the first gain of first frequency range differs from second amount of adjustment of second gain of second frequency range by more than first threshold amount.
