The extensive use of GNSS positioning, combined with the importance of precise geoid heights for transformation between geodetic and orthometric heights, brings up the discussion of the influence of data uncertainties and the use of variable density value... see more

En este trabajo se presentan estudios realizados sobre la determinación de geoidesmarinos preliminares en el océano Atlántico próximo a Argentina, utilizando datosde altimetría satelital y datos de gravedad marina. Los datos correspondientes a lamisión es... see more

 
The sea surface height can be determined by satellite altimetry, highlighting and understanding of oceanographic and geophysical phenomena arising today is a challenge that the comprehension requires many successive altimetrics missions.The Jason-2 missio... see more

This paper aims to present a new estimate for the vertical offset between both Brazilian vertical data: DVB-I, in Imbituba-SC, and DVB-S, in Santana-AP. Brazilian Fundamental Altimetric Network (BFAN) currently has over 69000 stations with known normal-or... see more

The geoid is an equipotential surface regarded as the altimetric reference for geodetic surveys and it therefore, has several practical applications for engineers. In recent decades the geodetic community has concentrated efforts on the development of hig... see more

A avaliacao do modelo geoidal oficial do Brasil, o MAPGEO2010, mostra que suas menores resolucoes situam-se nos estados do Maranhao e do Piaui, com discrepancias variando de cerca de }1 m em 500 km. Justamente, em tal regiao se faz necessar... see more

The combination of physical and geometric heights, required for geodetic purposes, uses Global Geopotential Models (GGMs), local geoid, or quasigeoid models. The geoid height and the height anomaly, provided by GGMs, are not accurate enough for most engin... 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
