Anti-spoofing Techniques for GNSS Receiver

Abstract
Spoofing can conduct effective interference with lower power than normal interference method,and it will become to a main jamming mode to the satellite navigation systems.By re-radiating the target signals or generating similar spoofing signals,spoofing interference can make the receivers derive inaccurate PVT information,which may disrupt the critical national infrastructure such as the power supply systems and the wireless communication systems.By analyzing the spoofing interference methods and the signal characteristic,we propose a series of anti-spoofing techniques,which can be a reference to the anti-spoofing design of the GNSS receivers used in the key civil infrastructures.
