On the Convergence of the h-p Finite Element Method for Solving Boundary Value Problems in Physical on new ways of gravity field modelling. The objective of this work is to study an application of the h-p finite element method for solving boundary value problems in physical geodesy. For the purpose of studying this method, we have formulated model boundary value problems with different boundary c

Domain Transformation and the Iteration Solution of the Linear Gravimetric Boundary Value Problem, A transformation of coordinates is used to express the relation between the description of the boundary of the solution domain and the structure of Laplace’s operator. The solution domain is carried onto the exterior of a sphere and the original oblique derivative boundary condition is given the fo

A New Argentinean Gravimetric Geoid Model: GEOIDEAR,ite-only global geopotential model (GGM) together with 560,656 land and marine gravity measurements. Terrain corrections were calculated for all gravity observations using a combination of the SRTM_v4.1 and SRTM30_Plus_v10 digital elevation models. For the regions that lacked of gravity observations

Traceability of the Hannover FG5X-220 to the SI Units,te FG5X is a free-fall gravimeter with a laser interferometer in Mach-Zehnder configuration which uses simultaneous time and distance measurements to calculate the absolute value of .. Because the instrument itself contains the necessary working standards for precise time and length measurements, it

,Evaluation of Robert Sterneck’s Historical Gravity Pendulum Measurements in the Czech Territory,. More than one hundred Sterneck’s pendulum gravity observations were performed between 1889 and 1895 on the Czech territory (i.e Bohemia, Moravia and Czech Silesia). Until present, thorough evaluation of the accuracy of these measurements was not accomplished. On the basis of original Sterneck’s fi

Ground-Satellite Comparisons of Time Variable Gravity: Results, Issues and On-Going Projects for thte satellite gravity observations (ground truth experiment) and point out possible issues. We first show results obtained in Europe where a moderate amplitude hydrological signal exists using both satellite (GRACE) and surface gravity measurements from the GGP (Global Geodynamics Project) network of
