National Time Scale of Bosnia and Herzegovina as Timing and Synchronization Source in Critical Infrastructure

In the following paper we elaborate the example of building national key infrastructure for time distribution and synchronization of critical end-users, presenting briefly the international timescale and its local realization as the most accurate time source in the country, the transport technology background and use cases in order to demonstrate advantages compared to the currently most used satellite systems solutions. We describe the experimental realization of a system developed for the distribution of time and frequency reference signals, synchronized with the national time scale, to the end user in Bosnia and Herzegovina. The architecture of the national timescale system and dissemination link technology is described. The achieved performances are evaluated in terms of accuracy, stability and availability, with the aim to demonstrate robust alternative time and synchronization service as a important segment of critical infrastructure for industry, business and the digitized society. A model for building the core infrastructure for distribution network is proposed.
