System and method for detecting GNSS spoofing attacks on a drone

摘要

System and method for detecting a GNSS spoofing attack (GNSS: global navigation satellite system) on a drone. The system comprises: a processing circuit; a plurality of GNSS antennas connected to a plurality of GNSS receivers, each of the plurality of GNSS receivers coupled to the processing circuitry; an RF absorber covering each of the plurality of GNSS antennas, the RF absorber enabling the plurality of GNSS antennas to identify a direction from which at least one GNSS signal is received; a memory coupled to the processing circuitry, the memory therein including instructions that, when executed by the processing circuitry, form the system: identify a plurality of properties associated with the at least one GNSS signal; to analyze the plurality of properties; determine whether the at least one GNSS signal is a spoofed signal based on the analysis of the plurality of properties.
