- Abstract
- In this paper, we present the Global Positioning System (GPS) jammer localization method using the carrier-to-noise density (C/No) measurements of the commercial GPS receivers, which are already installed nationwide in Korea. The jamming power directly affects the C/No measurements of GPS signals. Accordingly, we precisely make the C/No profiles of the GPS receivers correspond to the jamming power under jamming test environment. Then, the Received Signal Strength (RSS) of the jamming can be estimated by comparing the degraded C/No measurements and the corresponding C/No profile of the respective station. Finally, we determine the jammer location by using the RSS of the respective station and the propagation prediction model of the jamming signal.
