1. An apparatus for detecting interference in Global Navigation Satellite System (GNSS) signals comprising:
an RF splitter, configured for splitting a radio frequency (RF) input signal into a plurality of RF output signals;
a plurality of detectors associated with said RF splitter, each of said detectors comprising:
a bandpass filter configured for filtering one of said RF output signals into a respective GNSS frequency band; and
a peak detector configured for detecting a peak level of said filtered RF signal; and
a comparator associated with said plurality of detectors, configured for identifying a presence and an absence of interference in said GNSS frequency bands based on a comparison of said peak levels to respective thresholds, and for outputting a signal indicative of said presence and absence of identified interference;
wherein said RF splitter comprises:
an RF input configured for inputting said radio frequency signal;
a first internal splitter configured for splitting said input RF signal into a first RF signal and a second RF signal;
a second internal splitter configured for splitting said second RF signal into said RF output signals; and
an RF output configured for outputting said first RF signal.
