Spoofing and jamming detection and mitigation
A GNSS spoofer is a device able to broadcast a slightly more powerful signal than that received from the GNSS satellites. The spoofing signal is modified with respect to a normal GNSS signal in such a way as to cause the receiver to determine its position to be somewhere other than where it actually is. A spoofing attack can be very dangerous, and the research on this topic is especially devoted to both spoofing attack identification, and antispoofing techniques.
A GNSS jammer is a device able to create a disruptive interference, which prevents a GNSS receiver to receive the satellite signals. A jamming attack can be very dangerous, and the research on this topic is especially devoted to increase the robustness of GNSS receivers against this type of attack.
Experiments and simulation studies have been performed in the ISMB lab to identify methods to detect and mitigate spoofing and jamming attacks.
