Researchers develop tool to expose GPS signal spoofing in transit networks

The Oak Ridge National Laboratory (ORNL) has developed a portable detector that identifies GPS spoofing in real time, including during motion, to help protect transportation systems. Spoofing involves transmitting counterfeit signals that imitate authentic GPS transmissions and produce false information about location, time, or both. GPS jamming, another form of interference, overwhelms receivers with noise and blocks legitimate satellite signals. GPS spoofing overrides real satellite signals to trick a vehicle’s positioning software into following the … More →
