Abstract: Traditional dual-satellite geolocation is different to achieve high accuracy of satellite interference geolocation. To address this issue, a method of using Unmanned Aerial Vehicle (UAV) assist in obtaining high accuracy geolocation is presented. UAV receives uplink signal of the interference over the interference area, after measuring the interfering downlink signal transferred by satellite and UAV respectively at ground receiving station, moves the position of the UAV at different measuring times, multi-Time Difference of Arrival (TDOA) union equation of geolocation is introduced, then estimates the position of the interference using nonlinear least square algorithm. The results of the simulation show that the proposed method can improve the localization accuracy of satellite interference significantly, and it is a high accuracy and strong steady satellite geolocation method.
