As a typical aerospace technology application, Global Satellite Navigation System (GNSS) affects the national Positioning Navigation Timing (PNT) service. However, not all users are making good use of GNSS. In recent years, the most prominent phenomenon is the Unmanned Aerial Vehicle (UAV) “black flight”, which seriously affects the normal operation of civil aviation. To solve such problem, navigation spoofing can be used as an effective method to disrupt the flight of malicious UAVs. Currently, a centralized antenna is the most common way to transmit false navigation signals, but when the target receiver contains two receiving antennas or spatial filtering technology, this spoofing method is ineffective. Therefore, we aim at the distributed spoofers that each antenna emits a false navigation signal, and point out that this sophisticated attack will become the development trend of navigation spoofing in the future.
