Implantação do pilar ruju Botucatu na UNESP para integração ao Sistema Geodésico Brasileiro
(2008-01-01)
The objective of this work was to implant a geodesic pillar in the campus of Botucatu (Rubião Júnior) of the São Paulo State University (UNESP), using active stations of the Brazilian Net of Continuous Monitoring (RBMC) ...
Geodetic Reference Frame for the Americas
(Geodetical Information & Trading Centre, 2013-03)
SIRGAS (an acronym of the Spanish term for ‘Geocentric Reference System for the Americas’) is an international organisation under the umbrella of the International Association of Geodesy (IAG) and the Pan-American Institute ...
Fundamentos matemáticos envolvidos na realização do ITRS
(2006-07-01)
The mathematical fundamentals involved in the realization of a high precision reference system, taking into account solutions from VLBI, SLR, GPS and DORIS are presented. Each individual solution has its own deficiencies ...
Validation of the MAPGEO2010 and comparison with recent geopotential models
(UNIV FEDERAL PARANA, CENTRO POLITECNICOCURITIBA PR, 2012)
This paper presents the offorts to calculate the geoid model for Brazil. It is limited by 6 degrees N and 35 degrees S in latitude and 30 degrees W and 75 degrees W in longitude. The terrestrial gravity data for the continent ...
Conseqüências de uma tempestade geomagnética no posicionamento relativo com receptores GPS de simples freqüência
(2006-07-01)
The error associated with the ionosphere depends on Total Electron Content (TEC) of the ionosphere. The geomagnetic field exerts strong influence in the TEC variation, because it controls the movement of the electrons. ...
Transformação de Helmert generalizada no posicionamento de alta precisão: Fundamentação teórica e exemplificações
(2000-05-01)
The implementation of a referential that describes positions in the terrestrial surface, or near it, is divided in two phases: the definition (Reference System) and the materialization (Reference Frame). The positioning ...
Resultados preliminares de la interpretación del levantamiento magnético de los mares que circundan a Cuba
(1983)
Se informan los resultados preliminares en la interpretación de los levantamientos magnéticos marinos realizados en Cuba, en 1973 y 1975. Las profundidades se obtuvieron mediante la modificación de Veinberg del método de ...
Regional Model to Estimate Vertical Deformations Due to Loading Seasonal Changes
(Springer Verlag Berlín, 2016-01)
Surface mass transfer produces changes in the terrestrial geometric reference frame that are clearly detectable by GNSS techniques. These deformations are mainly observed in the vertical coordinate component and show ...
Revisiting the North Chile seismic gap segmentation using GPS-derived interseismic coupling
(Oxford University Press on behalf of The Royal Astronomical Society, 2013)
No major earthquake occurred in North Chile since the 1877Mw 8.6 subduction earthquake that
produced a huge tsunami. However, geodetic measurements conducted over the last decade in
this area show that the upper plate ...
Modelagem numérica da superfície na geração da planialtimetra segundo dados de quatro equipamentos topogríficos
(2008-01-01)
The aim of this present work was to compare planialtimetric charts obtained from different risings using two different theodolite types, a total station, and a precision level, used as control. Using a total station, an ...
