Black flights of Unmanned Aerial Vehicle (UAV) have occurred frequently in recent years, seriously endangering national defense and public safety. UAV mainly uses GNSS (Global Navigation Satellite System)/INS (Inertial Navigation System) integrated system for position and navigation. Due to the weak power and open structure of GNSS signals, it is possible to counter UAV through GNSS spoofing. This article proposes a satellite navigation spoofing algorithm for trajectory controlling of UAV. Through simulation analysis, it has been proven that the proposed spoofing method can make the target UAV deviate from the original trajectory and track the spoofing trajectory, and the estimated trajectory of the integrated navigation filter still tracks the original reference trajectory, achieving the goal of covert spoofing. In addition, in order to prevent UAV tracking loop from losing lock during the spoofing process, this article also explores the impact of radar detection accuracy on concealment. Simulation analysis shows that under high-precision radar detection conditions, the spoofing algorithm can control UAVtracking spoofing trajectory more accurately.
