Global Navigation Satellite System (GNSS) spoofing is a cybersecurity attack that provides fake PNT (Position, Navigation, Time) information. Hackers can take control of a GNSS receiver, remotely and undetectably. A GNSS spoofing attack is easy and inexpensive to create. It can influence critical functions, such as time-sync, speed control, steering, navigation, location, privacy, and more.
Spoofing attacks can produce conflicting data and incorrect system actions. Some failures can create time-sync position and velocity, and fleet-level and telematics problems.
