Analysis Center Citation

The individual Satellite Laser Ranging (SLR) solutions that contributed to the ITRF2020 combination product were computed by the following official International Laser Ranging Service (ILRS) Analysis Centers (listed in alphabetical order of their acronym identifier) using the SLR data obtained from the LAGEOS, LAGEOS-2, Etalon-1, and Etalon-2 satellites. The combined solution was generated by ITRS CC/Paris including the corresponding products from the other techniques, IVS, IGS, and IDS, resulting in the ITRF2020 combination product which was the basis for the development of SLRF2020. SLRF2020 was generated by the official ILRS Combination Center hosted by JCET/GSFC at Univ. of Maryland, Baltimore County (UMBC).

Description

Expanded set of SLR station positions and velocities in the ITRF2020 frame, includes historical sites NOT part of ITRF2020 and some very recently installed sites that came online in 2022. A small number of sites require special treatment with the addition of corrections to their "mean" positions (in this file) from the ITRS-distributed PSD model, due to "events" (e.g. earthquakes) or changes at the site. Users must apply these corrections cumulatively, to the linearly propagated positions from this file, by themselves. For more details, s/w and relevant correction files please visit the official ITRS site on ITRF2020.
