Research on GNSS generating spoofing jamming technology

Through the analysis of satellite navigation spoofing jamming signal, a GNSS generating spoofing jamming simulation system is constructed based on the GNSS generating spoofing jamming model. According to the receiver trajectory detected, the system can simulate the high precision and real-time GNSS spoofing jamming signals by receiving and analyzing the data information of the real navigation signal. The key algorithm and approach are put forward through analysis. Meanwhile, the key technology of GNSS generating spoofing jamming simulation system is designed and its implementation was presented. The spoofing jamming signal generated by the simulation system has a high fidelity and is not easy to be detected. It can provide effective means for jamming and guiding the receiver.
