Research on Spoofing Jamming of Integrated Navigation System on UAV

In order to conduct trajectory spoofing on Unmanned Aerial Vehicle (UAV) effectively, based on the analysis of the GPS spoofing jamming principle, combined with the control characteristics of the GPS/INS integrated navigation system to carry out the UAV spoofing trajectory planning. Firstly, according to the characteristics of UAV flight, the initial mobility constraint model of UAV is established. Secondly, the spoofing trajectory of UAV is planned under this constraint condition. Two trajectory planning algorithms for extension line and tangent line are proposed. Finally, simulation verification and analysis are conducted according to the proposed algorithms. The results show that both planning methods can deflect the UAV flight path, however, the planning method set by tangent is more strongly biased than the planning method set by the extension line, and the final spoofing effect is better.
