Optimization of Basepoint Configuration in Localization of Signal Interference Device

Precise navigation, as a method for guiding vehicles from one point to another, is an important subject these days especially in navigation of aircraft. Global satellite systems (GNSSs) are capable tools such purpose. Any intentional or unintentional interference signals may cause risks deadly accidents. Therefore, it tremendously control airports harbors and locate any existing radio frequency device. This localization can be done based on measuring time arrival (TOA), angle (AOA), difference (TDOA) the device sensors receivers at some basepoints. In this article, proposed arrivals optimizing configuration created by basepoints large grid points covering area. Furthermore, simulation test was performed verify theory, after that network designed optimized international Landvetter Airport Sweden. Our studies show when AOA used, our optimization more robust with respect resolution. addition, TDOA improves coverage over area significant reduction error points, but because special geometric shape Airport, not successful.
