“…Experiments with quantum levels measuring the difference in gravitational potentials between points on the Earth's surface with the use of transported hydrogen quantum clocks [1][2][3] based on the known Einstein's gravitational time dilation [4] have already been performed. In the present study, we propose to switch to the direct measurement of the gravitational frequency shift.…”

The effect of gravitational frequency shift doubling in a system of stationary and transported hydrogen quantum clocks in the Earth's gravitational field has been measured for the first time with an instability of 1·10-15. The clocks were separated in height by 34 m and connected by a radio channel based on optical fiber. The measured relative doubled "redshift" effect at this altitude was Delta fGR/fref=(-7.73± 1.61)· 10-15. Keywords: time dilation gravitational effect, gravitational frequency shift, quantum hydrogen clock.

Global navigation satellite systems, which provide high accuracy of navigation, in certain conditions (in tunnels, in closed rooms, in conditions of interference, etc.) have restrictions on their use. In this regard, in order to ensure “seamless” navigation in any conditions of the situation, it becomes necessary to develop new methods and means to increase the stability of navigation definitions. The article is devoted to the consideration of the problems of creating an integrated navigation system using measurements of the parameters of the Earth’s gravitational and magnetic fields. Requirements for meters of parameters of geophysical fields and navigation charts are considered, a number of new navigation meters, new methods and means of preparing navigation charts are proposed. The ways of development of relativistic geodesy and the possibility of using the achievements of gravitational-wave astronomy in gravimetry are considered.
