Various embodiments of the present technology generally relate to localization of one or more radio frequency interference (RFI) emitters. More specifically some embodiments relate to localization of RFI emitters that interfere with Global Navigation Satellite System (GNSS) receivers by integrating the location estimates of two or more localization techniques. Various embodiments may be used to more accurately estimate an interference source (e.g., an RFI emitter's location) than each localization technique separately.
