Abstract
A method for detecting and removing spoofing signals may include receiving, by a navigation or communications device, a radio frequency (RF) signal and performing an anti-spoofing assessment to detect a presence of a spoofing signal associated with the RF signal. The method may additionally include generating a replica of the spoofing signal in response to the spoofing signal being detected and subtracting the replica of the spoofing signal from the RF signal to provide a residual non-spoofed signal. The method may further include decoding the residual non-spoofed signal by the navigation or communications device.
