Research of Error Structure of Standard TIME Signal Synchronization System Via Digital Television Channels

The error structure of the standard time signal synchronization system via digital television channels was investigated. The relevance of this research is determined by changing the format of television broadcasting in Ukraine from analog to digital, which has necessitated the creation of a new standard time signal transmission system, adapted to the current format.An estimate of the basic permissible error of the system of standard time signal transmission via digital television channels, which has a value no less than similar estimates for foreign radio navigation systems was obtained.Based on evaluation of the basic allowable error of the standard time signal transmission system, it was shown that it is possible to ensure the required accuracy of reproduction of unit intervals of standard time scales in the process of determining the metrological characteristics of time and frequency measures when using the comparator for the standard time signals, transmitted via digital television channels.An important aspect is the independence of the metrological characteristics of the system of standard signal transmission via digital television channels on the technical condition of any foreign radio navigation systems, traditionally imposed on the consumer as sources of precise time-frequency synchronization
