Abstract. Highly stable frequency and time standards can be used to measure gravitational potential differences and orthometric height differences.
The paper reviews existing and prospective mobile (transportable) domestic and foreign time and frequency standards with an instability of 10–15–10–18, which can be used in quantum levels and when developing the “Quantum footgage” network. Information about Russian and foreign experiments on relativistic geodesy, which form the basis of quantum levels, is given.
Keywords: quantum level, time and frequency standard, quantum clock, optical frequency standard.
