A GPS Integrated Rammer and Spoofer Location (GIJLoc) determination system is proposed Conventional jammer locating equipment consists of dedicated electronic intelligence gathering platforms, which are practical against a relatively small number of high power, high value jammers, but are not practical against the expected GPS jamming three GPS jamming is likely to be ubiquitous, covering the battlefield with a large number o relatively low power jammers. More data is required to locate a large number of jammez than can be collected by a small number of dedicated platforms. Additional dedicated platforms are not practical. Future anti-jam GPS receivers will contain the equipment and information needed to act as data gathering platforms for locating Hammers and spoofers. Because such receivers will already be in the field, they are an ideal source for collecting the necessary data. A system architecture will be developed that collects data from future anti-jam GPS receivers and communicates that data to a central location where the location of jammers and spoofers are determined.
