Abstract

Disclosed herein are system, method, and computer program product embodiments for a GNSS interference and spoofing fast detection and mitigation system. A RF signal associated with a PNT device, such as a GNSS receiver, is received. The received RF signal is split into a plurality of sub-data signals. The received RF signal is re-routed by sending each of the plurality of sub-data signals to at least one of a processing module and a switching module. An anomaly associated with a second sub-data signal is detected. The anomaly is detected during a capture period of an adversarial attack on the PNT device, prior to corruption of any associated system depending on outputs from the PNT device. An output of a first sub-data signal of the plurality of sub-data signals is terminated based on the anomaly detected with the second sub-data signal.
