Overview of GNSS Spoofing Jamming Detection

In recent years, with the wide application of satellite navigation systems in military monitoring, precision agriculture, traffic monitoring, resource exploration, disaster assessment and other fields, improving the safety and robustness of satellite navigation systems has become a research hotspot. This paper first introduces the principle and classification of satellite navigation spoofing jamming. According to the process from satellite signal generation to the final realization of positioning and navigation and based on statistics, the current spoofing interference detection technology is divided into six categories：based on navigation data information, based on spatial processing, based on RF front-end processing, based on baseband digital signal processing, based on positioning and navigation operation results and based on machine learning, and the performance of the detection methods used in each category is compared. Finally, the future spoofing interference detection is prospected from two aspects of real-time detection and comprehensive detection.
