Recent results based on continuous GPS observations of the GIA process in Fennoscandia from BIFROST

M Lidberg, JM Johansson, HG Scherneck… - Journal of …, 2010 - Elsevier
We present the latest 3D velocity field of the Fennoscandian glacial isostatic adjustment

Refined least squares modification of Stokes' formula

LE Sjöberg - Manuscripta geodaetica, 1991 - Springer
The least squares modification of Stokes' formula reduces the impact of the errors stemming
from truncation, erroneous terrestrial gravity data and potential harmonics in a least squares …

A general model for modifying Stokes' formula and its least-squares solution

LE Sjöberg - Journal of geodesy, 2003 - Springer
Today the combination of Stokes' formula and an Earth gravity model (EGM) for geoid
determination is a standard procedure. However, the method of modifying Stokes' formula …

A computational scheme to model the geoid by the modified Stokes formula without gravity reductions

LE Sjöberg - Journal of geodesy, 2003 - Springer
In a modern application of Stokes' formula for geoid determination, regional terrestrial gravity
is combined with long-wavelength gravity information supplied by an Earth gravity model …

Deterministic, stochastic, hybrid and band-limited modifications of Hotine's integral

WE Featherstone - Journal of Geodesy, 2013 - Springer
Abstract Global Navigation Satellite System positioning of gravity surveys permits geoid
computation via Hotine's integral. A suite of modifications is presented so that the user can …

A new gravimetric geoid model for Sudan using the KTH method

A Abdalla, D Fairhead - Journal of African earth sciences, 2011 - Elsevier
Sudan is characterized by vast area with flat terrains in most of the country's regions and
therefore the existence of a high-resolution geoid model is considered very important …

Reformulation of Stokes's theory for higher than second‐degree reference field and modification of integration kernels

P Vaníček, LE Sjöberg - Journal of Geophysical Research …, 1991 - Wiley Online Library
An argument is put forward in favor of using a model gravity field of a degree and order
higher than 2 as a reference in gravity field studies. Stokes's approach to the evaluation of …

Computational stages of a new high-resolution 5 mm quasigeoid model for Estonia are
explained. Certain requirements for the quality and coverage of gravity data in the context of …

Integration of Residual Terrain Modelling and the Equivalent Source Layer Method in Gravity Field Synthesis for Airborne Gravity Gradiometer Test Site Determination

M Yang, WK Li, W Feng, R Pail, YG Wu, M Zhong - Remote Sensing, 2023 - mdpi.com
To calibrate airborne gravity gradiometers currently in development in China, it is urgent to
build an airborne gravity gradiometer test site. The site's selection depends on the …

Empirical comparison between stochastic and deterministic modifiers over the French Auvergne geoid computation test-bed

R Goyal, J Ågren, WE Featherstone, LE Sjöberg… - Survey …, 2022 - Taylor & Francis
Since 2006, several different groups have computed geoid and/or quasigeoid (quasi/geoid)
models for the Auvergne test area in central France using various approaches. In this …
