Analysis Center Citation
The individual solutions that comprise the REPRO2020 products were computed by the following official International Laser Ranging Service (ILRS) Analysis Centers (listed in alphabetical order of their acronym identifier) using the Satellite Laser Ranging (SLR) data obtained from the LAGEOS, LAGEOS-2, Etalon-1, and Etalon-2 satellites. The combined solutions of the REPRO2020 products were generated by the official ILRS Combination Center hosted by ASI and e-GEOS at CGS, Matera, Italy.

"The ILRS contribution to ITRF2020 consists of a pair of time series of weekly and bi-weekly station position estimates along with daily and 3-day averaged Earth Orientation Parameters (X-pole, Y-pole and excess Length-Of-Day (LOD)) estimated over 7-day arcs (1993.0 - 2021.0) and 15-day arcs for the period 1983.0-1993.0, aligned to the calendar weeks (Sunday to Saturday), starting from January 1983. Each solution is obtained through the combination of loosely constrained weekly/biweekly solutions submitted by each of the seven official ILRS Analysis Centers. Both, the individual and combined solutions have followed strict standards agreed upon within the ILRS Analysis Standing Committee (ASC) to provide ITRS products of the highest possible quality."
