The aim of the project is to demonstrate selected time and frequency transfer (UTC) techniques based on fibre optic networks. The implementation of such techniques, complementary to GNSS, is crucial to ensure the proper functioning of both the Critical National Infrastructure (CNI) and the various sectors of the economy. 

The project involves demonstrating two alternative scenarios for fibre-optic time and frequency transfer. The first focuses on achieving maximum transfer performance over distances of 700 km (corresponding to international connections). The second, dedicated to national and regional connectivity, places particular focus on robust and high-availability time and frequency transfer.
