Advances in time-frequency based geopotential determination
The state-of-the-art optical atomic clocks and the time-frequency signal transmission open a fresh field for gravity potential (geopotential) determination. Various methods, including optical fiber frequency transfer, satellite two-way, satellite common-view, satellite carrier phase, VLBI, tri-frequency combination, and dual-frequency combination, were developed to determine the geopotential differences using optical atomic clocks and then determine the geopotential at station B based on the geopotential at station A. This review elaborates the principles, methods, scientific objectives, applications, and relevant research trends of geopotential determination based on time-frequency signals.
