A ground-based source (12) of a jamming signal capable of disrupting a GNSS satellite-based navigation system, for example a GPS jammer, is located with a detector (20, 22, 24) carried by a suitable platform (10), for example an airborne UAV or missile. The detector, when the platform (10) is at a first location (16a),measures a characteristic of the jamming signal. The platform (10) and its detector are then moved to a chosen second location (16b),from which a further measurement of the jamming signal is made. The measurements made by the detectorare then used to determine the location of the source (12) of the jamming signal. |
