Assessing the Stability of an Integrated Timescale Synchronization and Delivery System Operating Under the Influence of Destabilizing Factors

Purpose: To develop a methodology for assessing the stability of time-frequency support systems exposed to various destabilizing factors. Methods: System analysis methods, the theory of network clock synchronization and unified time systems, methods for analyzing reliability, survivability and stability of technical systems, methods of mathematical modelling, and probability theory. Results: A methodology has been developed for evaluating the stability of time-frequency support systems exposed to destabilizing factors, based on reliability and survivability assessment. The developed methodology makes it possible to reflect the quality of time-frequency support system functioning under the influence of various destabilizing factors. Subsequently, it will form the basis for managerial decision-making under conditions of destabilizing influences. Theoretical significance: This methodology will allow a wide application of the system reliability and survivability theory ensuring the functional stability of telecommunication networks and time-frequency systems, as the stability of telecommunication networks and its subsystems is difficult to assess using traditional methods. Practical significance: The scientifically-based proposals mentioned above focus on ensuring the required stability of the functioning of time-frequency support systems under the influence of destabilizing factors, both natural and artificial, due to the lack of comprehensive study of the accurate time and frequency signal delivery outside of regular environments.
