Based on the analysis of GPS deception jamming theory, this paper considers the control feathers of the UAV GPS/INS integrated navigation system and designs an innovation detection rule for the UAV navigation system state estimation. Methods of direct track deception and track fusion are used to achieve the intrusive control of the navigation system and the control of the UAV's trajectory through the GPS deception jamming. The normalized innovation squared under two control modes is given through theoretical derivation and simulation analysis. The results show that the method of track fusion not only can realize the cheating of UAV trajectory, but also not easy to be checked, which provides an effective means of interference for GPS countermeasures.
