Gravity Compensation Using EGM2008 for High-Precision Long-Term Inertial Navigation Systems [PDF]

open access: yesSensors, 2016
The gravity disturbance vector is one of the major error sources in high-precision and long-term inertial navigation applications. Specific to the inertial navigation systems (INSs) with high-order horizontal damping networks, analyses of the error ...

Crustal structure beneath Cameroon from EGM2008 [PDF]

open access: yesGeodesy and Geodynamics, 2014
We used the Earth Gravitational Model (EGM2008) data sets to analyze the regional gravity anomalies and to study the underground structures in Cameroon. We first created a high-resolution Free-Air anomaly database, then corrected the gravity field of the

Qinghai-Tibet Plateau crustal thickness derived from EGM2008 and CRSUT2.0 [PDF]

open access: yesGeodesy and Geodynamics, 2014
Qinghai-Tibet Plateau is the most complex region for crustal thickness inversion, while high-resolution earth gravity model (EGM) makes it possible to obtain high precision gravity anomaly, which is a key parameter to depict the Earth’s inner structure ...

Determination of deflection of the vertical components by using global geopotential model EGM2008 [PDF]

open access: yesTehnika, 2018
This paper presents the determination of the vertical deflection components using the Global Geopotential Model EGM2008. The components are defined in two groups of points: 4083 points are relatively correctly distributed across the territory of Serbia ...

Direct regional quasi-geoid determination using EGM2008 and DEM: A case study for Mainland China and its vicinity areas [PDF]

open access: yesGeodesy and Geodynamics, 2015
Earth's gravity model (EGM) helps people better determine the figure of Earth, which is generally represented by a global geoid. For a considerable amount of practical applications, people use quasi-geoid to approximate the geoid, thus the quasi-geoid is

Assessment of recent GOCE-based global geopotential models and EGM2008 in Niger Republic [PDF]

open access: yesGeodesy and Cartography, 2019
In this study, we assessed recent GOCE-based Global Geopotential Models (GGMs) and EGM2008 in Niger.  The combined GGMs EIGEN_6C4, GECO and EGM2008 were evaluated up to their maximum degree and order (d/o) 2,190 to select the one for gravity database ...

Improving EGM2008 by GPS and leveling data at local scale [PDF]

open access: yesBoletim de Ciências Geodésicas, 2014
The development of the Earth Gravitational Model 2008 (EGM2008) model is a significant contribution for modeling the Earth's gravity and geoid. Recently, it can be confidently used versus geometric models following a simple refinement procedure. Several studies show that, EGM2008 can reach the accuracy of regional or local geoid models after modeling ...

Evaluation of EGM2008 by means of GPS Levelling Uganda [PDF]

open access: yesSouth African Journal of Geomatics, 2014
The global gravity model EGM2008 is evaluated in various regions of Uganda to assess if it is good enough for geodetic applications. The evaluation method involves comparison of geoid heights computed from the model with those computed at irregularly distributed GPS Levelling stations.
