Interference detection in a gnss signal

Abstract

An interference detector for detecting interference in Global Navigation Satellite System (GNSS) includes an RF splitter, multiple detectors and a comparator. RF splitter, splits a radio frequency (RF) input signal into multiple RF output signals which are provided to respective detectors. Each of the detectors includes a bandpass filter and a peak detector. The bandpass filter filters the RF output signal into a respective GNSS frequency band and the peak detector detects the peak level of the filtered RF signal. The comparator analyzes the peak detector outputs and identifies whether interference is present in the GNSS frequency bands by comparing the peak levels to respective thresholds. Based on this analysis, the comparator outputs a signal that indicates the presence and absence of identified interference in the GNSS frequency bands.
