METHOD FOR MEASURING THE PARAMETERS OF A GRAVITATIONAL FIELD USING A QUANTUM CLOCK CONNECTED BY RADIO COMMUNICATION CHANNELS, AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G01V7/04 G01V7/16 

FIELD: measuring equipment.

SUBSTANCE: invention relates to means for determining the parameters of the Earth's gravitational field. Mutual calibration of frequencies of master generators of stationary clocks (3) and relocated clocks (9) is carried out at the initial measuring point. A signal is sent from the stationary quantum clock (3) through the first radio link with the frequency of their master oscillator to the first input of the relocated frequency comparator (10) spatially aligned with the relocated quantum clock (9). The second input of the relocated frequency comparator (10) is fed with a signal from the relocated quantum clock (9) with the frequency of their master oscillator. With the help of a relocated comparator (10), the mutual frequency shift of the signals from the stationary (3) and relocated (9) clocks fed to the inputs of the relocated frequency comparator (10) is measured. From the relocated quantum clock (9) moved to a remote point, a signal is sent via the second radio link with the frequency of their master oscillator to the first input of the stationary frequency comparator (5) spatially aligned with the stationary quantum clock (3). The second input of the stationary comparator (5) receives a signal from the stationary quantum clock (3) with the frequency of their master oscillator. Using a stationary frequency comparator (5), the mutual frequency shift of the signals from the stationary (3) and relocated clocks (9) supplied to the inputs of the stationary frequency comparator (5) is measured. The measurement results from the output of the relocated frequency comparator (10) are transmitted via a radio link to the location point of the stationary quantum clock (3), where the measurement results obtained at the outputs of the stationary (5) and relocated (10) comparators are added. The doubled value of the calibration offset of the frequencies of the master generators of stationary (3) and relocated (9) clocks is subtracted from the resulting sum of measurements. Based on the obtained gravitational frequency shift, the difference between gravitational potentials and orthometric heights of the placement points of stationary and relocated quantum clocks is calculated.

EFFECT: improving the accuracy and efficiency of measuring the difference in gravitational potentials and orthometric heights.
