  Abstract

In this paper, we propose an application model of airborne communication relay UAV(Uumanned Aerial Vehicle) that finds out the crashed UAV in GPS-denied environment as using signals of the crashed UAV. For operation as making use of UAV, SWaP(Size, Weight and Power) constraints of UAV must be considered. In the proposed model, Airborne communication relay UAV transmits real-time signals of the crashed UAV and its location to the GCS. GCS estimates the location of the crashed UAV based on TDOA(Time Difference of Arrival) and provides the trajectory to airborne communication relay UAV for the crashed UAV to improve its accuracy of the estimated location. The proposed model implemented the army battalion battlefield with computer simulation. We improved the location accuracy through movement of airborne communication relay UAV for efficiently detecting the location of the crashed UAV in the battlefield. We confirmed effectively the possibility of locating the crashed UAV without using GPS information.
