Provided is a spoofing signal generating apparatus which generates signals to deceive an object having a global navigation satellite receiver. The spoofing signal generating apparatus comprises: a calculating unit which, on the basis of a first characteristic information containing at least one of the size, the location, and the speed of a first object received from a character analyzer for an object to be deceived, calculates one or more second characteristic information among a satellite capable of transmitting to the first object, a distance from the first object, a doppler frequency and a propagation path; a generating unit which generates a synchronization signal, which synchronizes a clock signal received from a GNSS receiver with a GNSS signal, and generates a spoofing signal by combining the synchronization signal with the second characteristic information; and a transmitting unit which transmits the spoofing signal in a direction of the first object.;COPYRIGHT KIPO 2017
