Recent applications in Earth sciences require geoid models to be determined with a sub-
centimetre internal error. Regional models of the geoid are usually determined using …

This paper represents a milestone in the UNB effort to formulate an accurate and self-
consistent theory for regional geoid determination. To get the geoid to a sub-centimetre …

For decades now the geodetic community has been split down the middle over the question
as to whether geoid or quasigeoid should be used as a reference surface for heights. The …

In this study, we compare six commonly used methods for the downward continuation of
airborne gravity data. We consider exact and noisy simulated data on grids and along flight …

The aim of this paper is to show a present state-of-the-art precise gravimetric geoid
determination using the UNB Stokes-Helmert's technique in a simple schematic way. A …

In many European countries, normal heights referred to the quasi-geoid as introduced by
Molodenskij in the mid-20th century are preferred to the classical height system that consists …

Most European states use MS Molodensky's concept of normal heights for their height
systems with a quasigeoid model as the reference surface, while the rest of the world rely on …

We report on testing the UNB (University of New Brunswick) software suite for accurate
regional geoid model determination by use of Stokes-Helmert's method against an …

This article discusses methods for selecting criteria used for stopping iterative regularization
methods applied to solving continuation of gravity observed at or outside the Earth's surface …

The precise regional geoid modelling requires combination of terrestrial gravity data with
satellite-only Earth Gravitational Models (EGMs). In determining the geoid using the Stokes …
