Abstract. It is proposed to develop a space quantum level on the basis of the projected Russian orbital station in near-polar orbit. The level is designed to determine the difference in gravitational potentials and orthometric heights between any points on the Earth’s surface, including the islands of the Arctic. The measurements are based on the effects of gravitational time dilation and gravitational frequency shift. The quantum level is based on the use of ground-based and on-board highly stable time and frequency standards, as well as ground-based quantum optical systems and radio engineering systems with first order Doppler effect compensation. A review of known technical solutions has been carried out, a relativistic theory of measurable effects has been developed, and the expected accuracy of measuring the difference in orthometric heights has been estimated.
Keywords: quantum level, Russian orbital station, relativistic time scale shift, gravitational frequency shift.
