The IERS was created in 1988 to establish and maintain a Celestial Reference Frame, the ICRF, a Terrestrial Reference Frame, the ITRF. The EOPs connect these two frames together. These frames provide a common reference to compare observations and …

Following the procedure already used for previous ITRF solutions, the ITRF2020 uses as input data time series of station positions and Earth Orientation Parameters (EOPs) provided by the Technique Centers of the four space geodetic techniques (VLBI, SLR, GNSS and DORIS), as well as local ties at colocation sites. Based on completely reprocessed ...

The objective of this web site is to distribute the International Terrestrial Reference Frame (ITRF) products. ITRF94 , ITRF96 , ITRF97 , ITRF2000 , ITRF2005 , ITRF2008 , ITRF2014 , ITRF2020 and ITRF2020-u2023 solutions are available for download.

the stability of the ITRF long-term origin, evaluated to be at the level of or better than 5 mm and 0.5 mm/yr for its time evolution, the agreement in scale between VLBI and SLR, at the level of 1-2 mm, with no drift, the growth of extrapolation errors of the ITRF2020 coordinates beyond the end of the ITRF2020 input data,

We also acknowledge the contribution of DGFI and JPL colleagues to the ITRF2014 analysis. The IERS ITRS Product Center is particularly grateful to all the institutions that provide the necessary investment for the space geodetic observatories which constitute the main ITRF foundation.

The International Terrestrial Reference Frame (ITRF) is the result of a combination of different terrestrial reference frames provided by the four space geodetic techniques (i.e. GNSS, SLR, DORIS and VLBI).
