With the wide application of GPS system in the military field, various countries are scrambling to carry out research on the technology of navigation countermeasure, the existing navigation countermeasure equipment is mainly based on oppressive interference technology, repeater spoofing attacks technology and asynchronous generated spoofing attacks technology, but the development of synchronous generated spoofing attacks technology is slow. Firstly, around the generation of spoofing attacks signal, this paper establishs the model of spoofing attacks, and introduces the methods of calculating the power of spoofing attacks signal, code phase delay, carrier frequency dopler and signal synchronization. Secondly, this paper presents the spoofing method of the object of interference. Finally, this paper designs a small GPS spoofing equipment, carries out a static spoofing test of the receiver and UAV, and carries out a outdoor spoofing experiment on the UAV. Through the above work, the rationality and operability of the method presented in this paper are verified.
Key words: spoofing attacks; navigation war; attack of EMI; spoofing signal
