The subject matter of the article is method of synchronization the ADS-B receivers system with MLAT technology use. The goal is to develop a method for synchronizing auto-dependent observation receivers ADS-B during conducting radar control with MLAT technology use. The task to analysis of the factors influencing the accuracy of the determination of airspace coordinates, a brief analysis of the ADS-B technology, and development the method of synchronization the ADS-B receivers system for the radar aircraft control with MLAT technology use. The methods used are: radar methods, methods of the theory of reception and processing of signals, determination of coordinates of air objects. The following results are obtained. The factors influencing accuracy of determination of coordinates of air objects are determined. The possibility of application of the technology of automatic dependent observation has been established to improve the accuracy of the determination of the coordinates of air objects. The method of synchronization the ADS-B receivers system for the radar aircraft control with MLAT technology use is developed. It is established that in order to better determine the coordinates of air objects, it is necessary to ensure the accuracy of synchronization of receivers of less than 1 microsecond. The method of synchronizing ADS-B receivers with radar control of the airspace with the use of MLAT technology has been developed, which provides the necessary precision of synchronization. The algorithm that implements the method of synchronization of the ADS-B receivers system using the technology of multilateration is proposed. Conclusions. The scientific novelty of the results obtained is as follows. It is established that the advantages of using the proposed ADS-B receiver synchronization method are the simplicity of the synchronization process, the possibility of using random objects of airborne objects equipped with ADS-B transponders and are in the action zone of the ADS-B receivers system as control objects. Further research suggests to use the proposed method of synchronizing the ADS-B receivers system and its practical use in conducting radar control of the airspace.Downloads
