Abstract:Spoofer poses a serious threat to Global Navigation Satellite Systems (GNSS). Currently, most methods for locating spoofed sources rely on multiple stationary receivers with known locations and time synchronization, whereas a new method for locating meaconer is proposed, which requires only one stationary receiver and thus avoids the complexities of synchronizing clocks and communicating among multiple receivers. The receiver's position does not need to be pre-determined, and the deceptive source can be located by observing the deceptive signal, using satellite position, velocity, and Doppler shift. This paper derives the positioning principle of the new algorithm and verifies its effectiveness through numerical analysis and simulated signal simulation.
