摘要：
Provided is a method and apparatus for removing a spoofing signal. The apparatus may convert a global positioning system (GPS) signal from an RF signal to an IF signal, and remove a spoofing signal based on whether the spoofing signal is present in the RF signal. The apparatus may obtain and track the spoofing signal using the IF signal, and generate a characteristic of the spoofing signal. The apparatus may generate an anti-spoofing signal by shifting a phase of the spoofing signal 180 degrees based on the characteristic of the spoofing signal.
