Within the International Laser Ranging Service (ILRS) DGFI actively participates as:

• Operation Center
• Global Data Centre
• Analysis Centre

DGFI acts as Operation Centre and Global Data Centre in its function as EUROLAS Data Centre (EDC) by

• Collecting and archiving of all SLR observation data
• Collecting and archiving of all other products generated by the ILRS
• Providing all the information via frequently updated Internet pages
• Mirror of the official ILRS Web pages

DGFI contributions as Analysis Centre are:

• Routinely processing of satellite laser ranging data of the global SLR station network to LAGEOS-1/2 and ETALON-1/2.
• For special investigations (e.g. determination of GM) inclusion of the data of other satellites with laser reflectors (e.g. Starlette and Ajisai).
• Daily and weekly computation of station positions and Earth Orientation Parameters (pole coordinates and length of day)
• Computation of global long-term SLR solutions with station coordinates and velocities.
• Daily computation of range and time biases from all SLR stations and publication through WWW
