Abstract
Satellite navigation spoofing technology induces the victim receivers to capture and track the forged navigation signal, so that the receivers work out the spoofed position and time. This paper presents a novel GPS spoofing method based on modifying navigation message, modify the handover word, spoof the calculated pseudo ranges and the satellite positions, then spoof the positioning result of receiver. The influence of the spoofing method on GPS receiver have been simulated, the results show that the proposed method has the approximate linear relationship with the eastern and northern spoofed distance, but has nonlinear relationship with the up spoofed distance. It has great significance to airspace supervision and defense.
