Based on the concept of Global Position System (GPS)/leveling, the satellite altimetry leveling (SAL) is first proposed to evaluate the marine geoid. SAL is derived by the difference among the mean sea surface (MSS), mean dynamic ocean topography (MD

Based on gravity frequency shift effect predicted by general relativity theory, this study discusses an approach for determining the gravity potential (geopotential) difference between arbitrary two points P and Q by remote comparison of two precise

The orthometric height (OH) system plays a key role in geodesy, and it has broad applications in various fields and activities. Based on general relativity theory (GRT), on an arbitrary equi-geo- potential surface, there does not exist the gravity fr

The Antarctic equivalent water height time series and the corresponding trends on a 1°×1° grid were derived based on 5-year GRACE data. The results show Amundsen in west Antarctica with strong negative rate exceeding –80 mm/a, Antarctic Peninsul

Based on the energy integral equation of satellite orbit-motion, some applied computation formulas for Earth gravity field recovery from satellite to satellite tracking data are presented, in which a strict expression of the difference of kinetic ene

Given the second radial derivative V rr (P)| ∂S of the Earth’s gravitational potential V(P) on the surface ∂S corresponding to the satellite altitude, by using the fictitious compress recovery method, a fictitious regular harmonic field rrV rr

The fictitious compress recovery approach is introduced, which could be applied to the establishment of the Runge-Krarup theorem, the determination of the Bjerhammar’s fictitious gravity anomaly, the solution of the “downward continuation” prob

Geoid determination on China Sea via corresponding deflection of the verticals is obtained from satellite altimeter data with the inverse Molodensky formula. In order to examine the accuracy of the geoid, two measures have been applied. Firstly the g

The global tectonic change deduced from geophysical research was first identified by space geodetic data from VLBI, GPS and SLR measurements. Whether using geodesic rates or using vertical velocities of stations, three kinds of data and their integra

We propose a test of the gravitational time dilation in general relativity by long term clock comparison between two stations separated in height. The geopotential difference between the two National time keeping centers in China, Lintong ( A ) and B
