By allowing user-defined modification of key parameters such as power, pseudo-range and navigation message content of one (“hoax”) signal with respect to a reference (“genuine”) signal, SimSAFE allows the user to emulate a spoofing attack whilst simultaneously monitoring (logs and displays) a range of receiver observables to evaluate the response of a receiver to the simulated attacks.

SimSAFE allows users to evaluate a receiver’s vulnerability to a wide range of simulated spoofing and data replay attacks. It supports assessment of spoofing detection, mitigation and signal authentication strategies in real time or post processing.

SimSAFE can use live sky for real signals and simulator output for spoof signals, or use a GNSS simulator to generate both “real” and “false” signals to allow dynamic scenarios.
