SLR: Data & Products

The ILRS collects, merges, archives and distributes Satellite Laser Ranging (SLR) and Lunar Laser Ranging (LLR) observation data sets of sufficient accuracy to satisfy the objectives of a wide range of scientific, engineering, and operational applications and experimentation. The SLR data collected from all the stations of the network are available through anonymous ftp or the web from the global data centers CDDIS and EDC

SLR Data Analysis PRODUCTS
The SLR data analysis has a relatively long history at the Matera Centro di Geodesia Spaziale (CGS). Started in 1984 with the on-site quality control, it is now a well established activity focused on the areas of tectonic plate motion, crustal deformation, post-glacial rebound and subsidence, Earth rotation and polar motion, time variations of the Earth gravitational field, center of mass of the total Earth system monitoring, International Terrestrial Reference System (ITRS) maintenance, satellite orbit determination.

Many geodetic products are provided on routinely basis compliant with the needs from international geodetic organisations (ILRS, IERS). Its continuous and rigorous contribution in support of the reference frame maintenance has been recognized by the ILRS Governing Board and the ASI/CGS was appointed as one of the official ILRS Analysis Centers (AC).
Due to the multi-technique nature of the CGS mission, geodetic technique combination methods and applications are a top priority objective of the data analysis activities performed at the Center. ASI-CGS is involved in combination activities aiming to provide specific products and as well as to test combination methodologies.
In June 2004 the Center was selected by the International Laser Ranging Service (ILRS) as its primary Official Combination Center (CC) for station coordinates and Earth Orientation Parameters.
