The applications of relativistic geodesy are increasingly being studied and exploited by scientists. Many studies on relativistic geodesy have obtained very positive results in measurement fields requiring high accuracy such as satellite geodesy, space geodesy, gravity geodesy, etc. This study presents the results of an experiment on determining the height difference between two points by comparing the frequencies of two optical atomic clocks, in Wuhan, China. The experiment results showed that the difference between the height difference determined by the clock frequency comparison method and the height difference determined by the leveling method was at the centimeter level.
