description: The subject of the graduate qualification work is synchronization system of GPS-signal. The given work is devoted to determination of the conditions and parameters of the formation of a false GNSS GPS signal for the successful substitution of the signal in the receiver. In this paper, using simulation modeling, the conditions for the successful substitution of GPS GNSS navigation signals in the receiver are determined depending on the time delay of the arrival of the spoofing signal relative to the true satellite signal and on the mutual frequency shifts of these signals at the receiving point. Methods of synthesis of GPS signals at the physical level and functional elements of their processing scheme are also considered. As a result of the conducted research, a range of values of permissible adjustments in frequency and time was obtained, within which a successful substitution of a true GPS navigation signal with a false one is possible, and a practical evaluation of the results was carried out. The terminological features of the subject area are considered and software tools are used to solve problems. The specialized software and mathematical software MATLAB is applied.
