Providing global position information to IFF transponders from IFF interrogators without GPS

Global Positioning System (GPS) systems has critical role on air platforms. This system is flight critical and other system installed in aerial platform are based on the location information provided by this system. However, this system can be easily affected by scattering/spoofing attacks due to low RF signal operating characteristic. The air platform can lose their global position and it can be threatened of flight safety if the presence of such attack some region on the earth. The operating principle of IFF system were analyzed about used from air traffic control radars. In this study, a global position information transfer method has been developed as backward compatible that does not conflict with the IFF operating scenarios of the air traffic control radar. In addition, an effective coding method has been developed within this method and the results have been observed. According to the results, it has been shown that global position information can be transferred effectively with low uncertainty values and high resolution.
