Currently, the development of global navigation satellite systems (GNSS) and their practical applications has made it necessary to improve the quality of time-frequency synchronization of consumers. High-precision transmission of the timestamp from the synchronization master (SM) to the synchronization slave (SS) using existing synchronization signals such as the pulse-per-second and the harmonic reference frequency signal is difficult due to the need to expand the bandwidth of the pulse signal transmission line time, mutual calibration of the delay of the timestamp transmission lines and the reference frequency, calibration of the active timestamp signal splitters for multiple access. A prospective combined signal of time-frequency synchronization (CSTFS), similar to the navigation signal of the GNSS, will bypass the limitations of the standard set of synchronization signals and achieve the necessary frequency-time synchronization error. However, the existing fleet of equipment used to solve the synchronization tasks is not suitable for the use of CSTFS. In this paper, we propose a method of using CSTFS to improve the accuracy of synchronization in the construction of synchronization systems based on existing types of equipment without its improvement. The proposed approach involves the connection to the SM and SS of specialized converters. Converters are connected on as short as possible cables with normalized impedance. The delay in the transmission of the time points (reference frequency phase) for each inverter can be calibrated. Unfortunately, this method does not provide an opportunity to improve the quality of traditional signals reproduction by the synchronization receiver, but allows using one of the main advantages of the CSTFS, such as: a single transmission line for all signal components and digital information; limited width of the signal spectrum; bidirectional signal transmission for the calibration of the transmission line; the possibility of transferring additional service information; synchronization of SM and SS at large distances; construction of synchronization networks using passive couplers.
