Methods and apparatus for detecting of spoofing or jamming activities near a train or other railroad assets uses a message sent from each of a plurality of base stations receiving a wireless packet transmitted by a radio of a railroad asset that reports the PNT information determined by the radio using GNSS and a timestamp for the time of arrival of wireless packet at the base station. The position of the asset is then calculated based on the time arrival of the wireless packet at each base station and compared to the reported position. A warning is generated if the difference exceeds a predetermined threshold.
