This invention is for a device that can locate a GPS jamming signal. It includes a direction finder 210. Antennas 206A to 206D receive radio signals, and the receivers 208A to 208D each output a signal which is fed to the direction finder. There is also a combiner 216 that takes video data stream from a video camera 110 and produces a source indicator on the video data that corresponds to the radio signal source, i.e. the jamming signal. It may also include a video monitor that can display the video generated by the video camera with the one or more radio source indicators. There may also be a calibrator 212 that ensures that the video data stream from the video camera and the direction signal are aligned correctly. The camera and direction finder can also be combined into a single hand-held unit, as shown in figure 1. |
