Anti-Unmanned Directional Drive-Off Method Under Integrated Navigation Mode

To realize the defense task of precise directional drive off of unmanned combat system in the target area, an anti-unmanned directional drive-off method under SINS(Strapdown Inertial Navigation System)/GPS(Global Positioning System) integrated navigation mode is proposed in this paper, which is suitable for the security defense of important places, urban public security protection and anti-terrorism and stability maintenance in sensitive areas. Firstly, this paper constructs a seven dimensional SINS/GPS integrated navigation model of unmanned combat system including horizontal position, velocity and attitude, and uses discrete Kalman filter for data fusion; Then, combined with the coupling relationship between various state parameters of SINS/GPS integrated navigation, the controllability and stability of false satellite signal acting on the position output of integrated navigation are analyzed, and then the feasibility of satellite navigation spoofing under SINS/GPS integrated navigation mode is deduced; Finally, the false satellite signal is designed and constructed to make the position estimation of SINS/GPS Integrated Navigation drive away accurately. The simulation and experimental results verify the effectiveness and correctness of the anti-unmanned directional drive-off method under the integrated navigation mode. Note to Practitioners—This work is motivated by the need for the defense task of precise directional drive off of unmanned combat system in the target area. Most unmanned combat platforms adopt the integrated navigation mode with satellite navigation system as an auxiliary means. It can be challenging for researchers and practitioners to drive off the unmanned combat system which adopt the integrated navigation mode in the target area by the existing spoofing methods. Therefore, this paper presents an accurate directional displacement method against unmanned under the SINS/GPS integrated navigation mode and the effectiveness of the proposed method is verified by UAV spoofing simulation and test. This paper provides researchers and practitioners with comprehensive reference sources in anti-Unmanned directional drive-off method under integrated navigation mode, which can help them develop suitable solutions to drive off the unmanned combat system which adopt the integrated navigation mode in the target area.
