FIELD: measuring.
SUBSTANCE: invention relates to tools for determining the parameters of the gravitational field of the Earth. Substance: the time scales of a stationary atomic clock and a mobile atomic clock undergo mutual calibration. After the mutual calibration, the mobile clock is moved from the starting point on the surface of the Earth to the measurement point by a first random route. The mobile clock is kept in a stationary state at the measurement point for the selected time interval and then moved back to the starting point by another random route optionally identical to the first route. The current coordinates and speed of the mobile clock are herein measured at each stage of the movement of the mobile clock using a navigation receiver. The relativistic offsets of the time scale of the mobile clock are calculated. At the end of each stage, corrective adjustments equal in magnitude and reverse by sign to the relativistic offsets calculated at said stage are calculated and entered onto the time scale of the mobile clock. The difference between the readings of the time scale of the mobile clock and the time scale of the stationary clock is then measured at the starting point, and the difference between the gravitational potentials and the orthometric altitudes of the starting point and the measurement point is determined. Apparatus for the implementation of the method includes a stationary platform (1) and a mobile platform (2) linked by a duplex communication channel. A stationary atomic clock (3), a time scale comparison apparatus (4), and a computing apparatus (5) are positioned on the stationary platform (1). A mobile atomic clock (6), a navigation receiver (7), a computing apparatus (8), and a time scale correction apparatus (9) are positioned on the mobile platform (2).
EFFECT: increase in the accuracy of measuring the difference in gravitational potentials and orthometric altitudes.
