Abstract: Global Navigation Satellite System (GNSS) interference detection may be provided. A satellite tracking table for a first Access Point (AP) may be created. The satellite tracking table may include a listing of a plurality of satellites of a Global Navigation Satellite System (GNSS) available for the first AP and expected satellite parameters for each of the plurality of satellites. A derived satellite parameter may be determined from a received GNSS signal. The derived satellite parameter may be compared with an corresponding expected satellite parameter. The corresponding expected satellite parameter may be determined from the satellite tracking table. An interference event may be determined when the derived satellite parameter differs from the corresponding expected satellite parameter by at least a predetermined amount.
