To synchronize the communication equipment it is necessary to build frequency-time support systems. Time synchronisation means simultaneous synchronisation of master and slave devices by frequency, phase and date. In existing networks the synchronisation method based on NTP/SNTP, RTR protocols and time signal distribution devices is widely used. However, there are many factors affecting the time transmission accuracy during synchronisation from specialised equipment installed together with synchronised communication equipment. Thispaper considers the relevance of application of integrated small-size time servers synchronised from GNSS, their advantages and disadvantages in comparison with classical methods of synchronisation.
