1316. An analysis of the equipotential surface waves of the Earth’s gravity field

A detailed analysis is performed on the influence that the celestial bodies have on the equipotential surface of the Earth’s gravity field. The necessary background is developed in order to progress a new more intelligent methodology of estimating the influence that the celestial bodies have on the geodetic measurements. Previous studies demonstrate that this impact strongly depends on the elasticity of the solid Earth. It is also unequal on different equipotential surface waves. Some results of current investigations are presented, which demonstrate the waves of the Earth’s gravity field influenced by the celestial bodies. The assessment of changes in an equipotential surface is required when reducing the measurement data into a common coordinate system of a definite epoch. © JVE INTERNATIONAL LTD.
