In global navigation satellite systems (GNSS), a spoofing attack attempts to deceive a GNSS receiver by broadcasting fake GPS or other GNSS signals, structured to resemble a set of normal GNSS signals, or by rebroadcasting genuine signals captured elsewhere or at a different time. GNSS spoofing is a more sophisticated and deceptive practice than GNSS jamming, which merely blocks affected devices from being able to use GNSS systems at all.
