Recently, there is an increased interest in studying and defining the Local and Regional Geoid Model worldwide, due to its importance in geodetic and geophysics applications. The use of the Global Positioning System (GPS) is internationally growing, yet t... see more

Recently, there has been an increased interest in studying and defining the Local and Regional Geoid Model worldwide, due to its importance in geodetic and geophysics applications.The use of the Global Positioning System (GPS) is internationally growing, ... see more

There are several techniques for determining geoid heights using ground gravity data, the geopotential models, the astro-geodetic components or a combination of them. Among the techniques used, the Remove-Compute-Restore (RCR) technique has been widely ap... see more

In this study, test-region global positioning system (GPS) control points exhibitingknown first-order orthometric heights were employed to obtain the points of planecoordinates and ellipsoidal heights by using the real-time GPS kinematicmeasurement method... see more

The geoid is the reference surface used to measure heights (orthometric). These areused to study any mass variability in the Earth system. As the Earth is representedby an oblate spheroid (Ellipsoid), the geoid is determined by geoidal undulations(N) whic... see more

The purpose of this manuscript is to compute and to evaluate the geoid model in the State of São Paulo from two methodologies (Stokes’ integral through the Fast Fourier Transform - FFT and Least Squares Collocation – LSC). Another objective of this study ... see more

Earth Gravitational Model 2008 merupakan (EGM2008) model geoid yang didapatkan dengan kombinasi data terestrial, data altimetri dan data gayaberat airborne. Pemanfaatan data EGM2008 untuk pemodelan geoid di Indonesia ketelitiannya masih rendah. Dalam memo... see more

O advento da tecnologia GNSS (Global Navigation Satellite System) possibilitou muitos avanços em diversas áreas da ciência e engenharia. Porém, as altitudes obtidas a partir do posicionamento com esse sistema são de natureza puramente geométrica e sem rel... see more

Apresenta-se análise qualitativa das alturas geoidais associadas aos modelos geopotenciais globais combinados: EIGEN-GL04C advindo da missão gravimétrica GRACE (Gravity Recovery and Climate Experiment) e da missão laser (LAGEOS - Laser Geodynamics Satelli... see more
