Basic research for the geodynamics program [PDF]

open access: yes
Some objectives of this geodynamic program are: (1) optimal utilization of laser and VLBI observations as reference frames for geodynamics, (2) utilization of range difference observations in geodynamics, and (3) estimation techniques in crustal ...

Gravitomagnetism and gravitational waves

open access: yes, 2010
After extensively reviewing general relativistic gravitomagnetism, both historically and phenomenologically, we review in detail the so-called magnetic components of gravitational waves (GWs), which have to be taken into account in the context of the ...

VLBI analyses with the GINS software for multi-technique combination at the observation level

open access: yes, 2007
A rigorous approach to simultaneously determine a Terrestrial Reference Frame (TRF) and Earth Orientation Parameters (EOP) is now currently applied on a routine basis in a coordinated project within the Groupe de Recherches de G\'eod\'esie Spatiale (GRGS)

The future of spaceborne altimetry. Oceans and climate change: A long-term strategy [PDF]

open access: yes
The ocean circulation and polar ice sheet volumes provide important memory and control functions in the global climate. Their long term variations are unknown and need to be understood before meaningful appraisals of climate change can be made. Satellite

Global Ocean Mass Change Estimation Using Low‐Degree Gravity Field From Satellite Laser Ranging

open access: yesGeophysical Research Letters
Satellite laser ranging (SLR) is a well‐established geodetic technique for measuring the low‐degree time‐variable gravity field for decades. However, its application in mass change estimation is limited by low spatial resolution, even for global mean ...
