Description
GFZ operates an Analysis Center (AC) of the ILRS - International Laser Ranging Service since 2003. As such we participate in all activities and pilot projects of the ILRS Analysis Working Group. We routinely analyse LAGEOS-1 and -2 Satellite Laser Ranging (SLR) data of the global network, including the SLR station in Potsdam. The analyses are used to generate official daily and weekly products which include loosely constrained station position estimates and earth orientation parameters (EOPs), which are input to the ILRS combined solution. The daily combinations serve mainly EOP prediction needs of the International Earth Rotation and Reference Systems Service (IERS). Every few years, the long-term SLR time series are reprocessed and serve as contribution to the new International Terrestrial Reference Frame (ITRF).
