In this study, a spoofing algorithm for a ground-unmanned platform equipped with a GNSS/INS-integrated navigation system is proposed, which can be used to control and defend illegal ground unmanned platforms. First, the unmanned platform satellite navigation spoofing process is modeled as the response process of a first-order control system. Based on the response time of the system, the relationship between the spoofing start point and the spoofing success point is established. Then, the influence of satellite navigation spoofing on the integrated navigation system parameters of unmanned platforms is analyzed, and the maximum spoofing offset can be applied under the premise of maintaining the covertness of spoofing is obtained. It is used as the maximum distance value for searching spoofing target points, and the constraints of path search and matching are determined. Finally, the spoofing satellite signals satisfying the constraint conditions are obtained by the breadth-first search algorithm, and the unmanned platform is spoofed. The experimental results show that the method can successfully spoof the vehicle platform to follow the searched target route to the preset target point under the constraint of the road network.
