A GNSS Anti-Spoofing Technology Based on Power Detection

摘要

In anti-spoofing technologies for Global Navigation Satellite System(GNSS), power detection technology was one of the more reliable and easy-to-implement technologies. Based on the principle of power detection technology, the detection statistics for power detection were studied. The methods of anti-spoofing and threshold in power detection were given. Through testing and data analysis, the performance evalution and application scenarios of power detection technology were given. This technology can be directly applied to the receiver signal processing algorithm to improve the anti-spoofing ability of receiver.
