Različni postopki za izračun odklonov navpičnice: primer območja pod Krvavcem ( = Different aspects of the computation of vertical deflection: case study in the area of Krvavec) [PDF]

Geodetski Vestnik, 2018
In coordinate calculation from terrestrial measurements, the reduction due to the Earth's gravity field should be one of the main topics of consideration. The problem is of extreme importance especially in steep areas, where geoid surface is not parallel

Will the recently approved LARES mission be able to measure the Lense-Thirring effect at 1%?

, 2008
After the approval by the Italian Space Agency of the LARES satellite, which should be launched at the end of 2009 with a VEGA rocket and whose claimed goal is a about 1% measurement of the general relativistic gravitomagnetic Lense-Thirring effect in ...

Effective elastic thickness in the Central Andes. Correlation to orogenic deformation styles and lower crust high-gravity anomaly [PDF]

, 2018
Global studies have assessed the importance of elastic thickness (Te) on orogenic evolution, showing that the style and nature of upper crustal shortening are influenced by the inherited lithospheric strength. Thus, pioneer works have identified that the

The quasigeoid modelling in New Zealand using the boundary element method

Contributions to Geophysics and Geodesy, 2010
We compile a quasigeoid model at the study area of New Zealand using the boundary element method (BEM). The direct BEM formulation for the Laplace equation is applied to obtain a numerical solution to the linearized fixed gravimetric boundaryvalue ...

Assessment of EGM2008 over Britain using vertical deflections, and problems with historical data [PDF]

Survey Review, 2013
AbstractVertical deflections synthesised from the Earth Gravitational Model 2008 (EGM2008) agree with astrogeodetic vertical deflections observed over mainland Britain to within ∼1·2″ RMS (north–south) and ∼1·4″ RMS (east–west), which is commensurate with values reported for North America, Australia and parts of continental Europe.

Evaluation of gravity field model EIGEN-6C4 by means of various functions of gravity potential, and by GNSS/levelling

Geoinformatics FCE CTU, 2015
The combined gravity field model EIGEN-6C4 (Förste et al., 2014) is the latest combined global gravity field model of GFZ Potsdam and GRGS Toulouse. EIGEN-6C4 has been generated including the satellite gravity gradiometry data of the entire GOCE mission (

Evaluating SWOT in the Coastal Zone: Comparisons With Tide Gauge and Airborne LiDAR in the Bristol Channel and Severn Estuary, UK

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Traditional nadir altimeters struggle with coastal water surface elevation (WSE) measurement and fine‐scale river‐estuary interactions, due to land‐water signal interference and their wide inter‐track spacing. The wide‐swath Surface Water and Ocean Topography (SWOT) mission, using a new Ka‐band radar interferometer, aims to address these ...

Use of recent geoid models to estimate mean dynamic topography and geostrophic currents in South Atlantic and Brazil Malvinas confluence

Brazilian Journal of Oceanography, 2012
The use of geoid models to estimate the Mean Dynamic Topography was stimulated with the launching of the GRACE satellite system, since its models present unprecedented precision and space-time resolution. In the present study, besides the DNSC08 mean sea

An Assessment of State-of-the-Art Mean Sea Surface and Geoid Models of the Arctic Ocean: Implications for Sea Ice Freeboard Retrieval [PDF]

, 2017
State-of-the-art Arctic Ocean mean sea surface (MSS) models and global geoid models (GGMs) are used to support sea ice freeboard estimation from satellite altimeters, as well as in oceanographic studies such as mapping sea level anomalies and mean ...

Performance evaluation of the Earth Gravitational Model 2008 (EGM2008) – a case study

South African Journal of Geomatics, 2017
Ghana’s local geodetic reference network which is based on the War Office 1926 ellipsoid was established using astro-geodetic observations during the British Colonial era with data in latitude, longitude and orthometric height (𝜑,𝜆,𝐻) without the existence of ellipsoidal height.
