Researchers move in the right direction, develop powerful GPS interference alarm

Oak Ridge National Laboratory developed a portable GPS interference detector combining a software-defined radio, an embedded GPU, and a new RF-analysis method to detect both GPS spoofing and jamming — including cases where fake and real signals are equally strong. The device is aimed at protecting cargo transportation (with tests showing sensitivity exceeding industry systems) and could help mitigate incidents such as cargo theft and threats to aviation and other critical services.
