Aircraft flight safety is largely dependent on the performance of systems having various purposes. One of the systems is ADS-B intended for air traffic management by constructing trajectories of aircraft motion with efficient use of airspace. The analysis of main methods of designing the equipment, demodulating and decoding the signals in data links is therefore a relevant objective which can increase the efficiency of air transportation at the required level of flight safety.   

Key words: ADS-B, systems of symbol synchronization, quadrature demodulator, quadrature signal, hardware-software receiver, preamble detector.
