ASI/CGS gravity solutions
The data collected from the SLR network contribute to the study of the Earth system, as a whole. Ad hoc analyses are made at ASI/CGS to derive time series of low degree geopotential zonals and geocenter.
- Time series of low-degree geopotential
zonals and their secular drifts. Description
and results
- Time series of C2,0 C2,1 and S2,1
obtained from the analysis of SLR observations of a constellation
of seven geodetic satellites (Stella, Starlette, Ajisai, the
two Lageos, the two Etalon) acquired by the worldwide network,
data are available on request. A description is available in
the proceedings of the 18th International Workshop on Laser
Ranging (http://cddis.gsfc.nasa.gov/lw18/docs/papers/Session2/13-01-11-Luceri.pdf
).
- Geocenter time series
are routinely produced as translation with respect to a reference
ITRF. Some plots of the series w.r.t. ITRF2008 are shown below,
data are available on request.
