Analytical attitude propagation with non-singular variables and gravity gradient torque for spin stabilized satellite
(Elsevier B.V., 2007-01-01)
An analytical approach for the spin stabilized satellite attitude propagation is presented using the non-singular canonical variables to describe the rotational motion. Two sets of variables were introduced for Fukushima ...
GOCE satellite derived gravity and gravity gradient corrected for topographic effect in the South Central Andes region
(Wiley Blackwell Publishing, Inc, 2012-08)
Global gravity field models, derived from satellite measurements integrated with terrestrial observations, provide a model of the Earth's gravity field with high spatial resolution and accuracy. The Earth Gravity Model ...
Integrated marine gravity field in the Brazilian coast from altimeter-derived sea surface gradient and shipborne gravity
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Sea surface gradients derived from the Geosat and ERS-1 satellite altimetry geodetic missions were integrated with marine gravity data from the National Geophysical Data Center and Brazilian national surveys. Using the ...
The seismically active Andean and Central American margins: Can satellite gravity map lithospheric structures?
(2011-11-17)
The spatial resolution and quality of geopotential models (EGM2008, EIGEN-5C, ITG-GRACE03s, and GOCO-01s) have been assessed as applied to lithospheric structure of the Andean and Central American subduction zones. For the ...

Moho structure of Central America based on three-dimensional lithospheric density modelling of satellite-derived gravity data
(2012-05-23)
The Central American isthmus hosts a highly variable Moho structure due to the diverse origin and composition of the crustal basement and the influence of large-scale neotectonic processes. Gravity data from the combined ...

Gravity anomalies over extinct spreading centres: A new evidence of an aborted ridge in the South Atlantic Ocean
(2019-01-01)
An aborted ridge has been suggested in the Vema region, South Atlantic Ocean, and we investigate it in terms of residual gravity anomalies and half spreading rate. Gravity signature over extinct spreading centres displays ...
Seismic structure along the South American subduction zone using satellite gravity data
(Elsevier, 2019)
Great megathrust earthquakes occur regularly along convergent plate margins such as the Nazca-South American boundary. This is shown by historical and recent ruptures along this margin. Satellite missions designed for ...
