We demonstrated a concept of a navigation system in MEO based on master clocks in the GEO orbit and two-way optical/microwave links to transfer their stable frequency to the navigation satellites in MEO orbit (eith

Clocks on board GNSS have become so stable that it makes interesting to steer their frequen
