ANTI-SPOOFING METHOD AND APPARATUS

摘要

Disclosed is an anti-spoofing method and apparatus. The anti-spoofing method comprises the steps of (a) receiving a global positioning system (GPS) signal; (b) converting the GPS signal into a two dimensional (2D) surface of a Doppler frequency and a code phase to generate a plurality of channel information according to whether a plurality of peaks are detected; and (c) detecting a spoofing signal from the GPS signal obtained through the plurality of channel information, and selecting the GPS signal excluding the detected spoofing signal.
