Determining geopotential difference via relativistic precise point positioning time comparison: A case study using simulated observations
Chenghui Cai, Wen-Bin Shen, Ziyu Shen +2
According to general relativity theory (GRT), the geopotential difference (GD) can be determined by comparing the change in time difference between precise clocks using the precise…
Preliminary experimental results of determining the geopotential difference between two synchronized portable hydrogen clocks at different locations
Wen-Bin Shen, Kuangchao Wu, Xiao Sun +2
Here, we provide preliminary experimental results of the geopotential determination based on time elapse comparisons between two remote atomic clocks located at Beijing and Wuhan,…
Unification of global height system at centimeter level using precise frequency signal links
Ziyu Shen, Wen-Bin Shen, Shuangxi Zhang
The realization of International Height Reference System (IHRS) is one of the major tasks of the International Association of Geodesy (IAG). A main component of the IHRS realizatio…
Gravity field modeling using space frequency signal transfer technique between satellites
Ziyu Shen, WenBin Shen, Xinyu Xu +1
Here we provide an alternative approach to determine the Earth's external gravitational potential field based on low-orbit target satellite (TS), geostationary satellites (GS), and…
New evidences for the fluctuation characteristic of intradecadal periodic signals in length-of-day variation
Hao Ding, Yachong An, Wenbin Shen
The intradecadal fluctuations in the length-of-day variation (dLOD) are considered likely to play an important role in core motions. Two intradecadal oscillations, with 5.9yr and 8…
Formulation of a Triaxial Three-Layered Earth Rotation: I. Theory and Rotational Normal Mode Solutions
Zhiliang Guo, Wenbin Shen
In this study, we formulated a triaxial three-layered anelastic Earth rotation theory con-sidering various core mantle couplings, including the pressure and gravitational couplings…
