description: The subject of the graduate qualification work is âMeteor burst synchronization systemsâ. The given work is devoted to evaluate the accuracy of synchronization in meteor radio communication systems using the PTP protocol, taking into account possible software delays. This work is devoted to assessing the influence of the parameters of the meteor radio communication channel on the accuracy of synchronization in the implementation of the PTP. A simulation model of a meteor synchronization system has been implemented, to increase the synchronization accuracy of which it is proposed to introduce a jitter estimator on the receiving module. The estimates and dependences obtained show that, at a fixed scale shift, an increase in jitter leads to a decrease in the accuracy of the shift estimate. In addition, the dependences obtained show exactly how the synchronization accuracy will deteriorate with increasing jitter. With additional estimation of jitter and corresponding adjustment of the calculated shift of the time scales, the synchronization accuracy can be increased. The implemented model makes it possible to evaluate the synchronization accuracy of the meteor synchronization system to ensure the coordinated operation of devices and applications that process data in real time or monitor and control in order to record emerging events and respond to them in a timely manner. For example, in systems for early warning of natural disasters and in systems for collecting data from various sensor systems or when replacing backup radio channels for transmitting information at industrial facilities in the North.
