A user-friendly software package for modelling gravimetric geoid by the classical Stokes-Helmert method Open
With the progress in Global Navigation Satellite Systems (GNSS) technology, accurate geoid modelling has started to play an essential role in geodetic applications such as establishing height datum as a continuous surface model and related…

Digitisation and analysis of historical vertical deflections in India Open
We describe the [somewhat tedious] process of digitising from a 1955 report that lists over 1000 vertical deflections in India and some surrounding countries. It involved error-checking with closed-loop tests and resolution of an ambiguity…

Optimal choice of the number and configuration of VLBI Global Observing System in India Open
<p>The need of the geodetic VLBI stations in South Asia region has been discussed and suggested for decades to have a uniform global VLBI network and relatively more accurate realisation of ITRF. With the recent initiative of Nationa…

Empirical comparison between stochastic and deterministic modifiers over the French Auvergne geoid computation test-bed Open
© 2021 Survey Review Ltd. 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 contribution, we compute and compare q…

Flight Height of UAV and Its Influence on the Precise Digital Elevation Model of Complex Terrain Open
The application of lightweight Unmanned Aerial Vehicle (UAV) has been increasingly common in 3D topographic surveys. Especially in the complex terrains such as open-pit mines, where the elevation is rapidly undulating, the UAV based mappin…

Subtleties in spherical harmonic synthesis of the gravity field Open
<p>Spherical harmonic synthesis (SHS) can be used to compute various gravity functions (e.g., geoid undulations, height anomalies, deflections of vertical, gravity disturbances, gravity anomalies, etc.) using the 4pi fully normalised…
