Subject: <b>ITRF2020-u2024</b> is available on line<br>
<br>
Dear ITRF Users and Colleagues,<br>
<br>
Three years after its release, the ITRS Center has initiated
regular (yearly) updates of ITRF2020.<br>
<br>
The IERS ITRS Center at IGN has the pleasure to announce to the
community the<br>
availability of the <b>ITRF2020-u2024</b> solution at the
dedicated web site:<br>
<br>
<a class="moz-txt-link-freetext" href="https://itrf.ign.fr/en/solutions/ITRF2020-u2024">https://itrf.ign.fr/en/solutions/ITRF2020-u2024</a><br>
<br>
ITRF2020-u2024 is the second ITRF020 update, generated by adding
four years (2021.0 – 2025.0) of data after the end of the
ITRF2020 input data.<br>
<br>
I want to take this opportunity to acknowledge the enormous
efforts of the IAG Services (IDS, IGS, ILRS, IVS) and their
Analysis and Combination Centers for their contributions by
providing extended time series of station positions and Earth
Orientation Parameters (EOPs).<br>
The quality of the ITRF2020-u2024 is certainly benefiting from
these technique improved solutions. Many thanks to a number of
institutions and individuals for their contributions to the
ITRF2020-u2024 project.<br>
<br>
The ITRF2020-u2024 web site contains the most important results
and information<br>
regarding the ITRF2020-u2024 combination. It will be updated as
necessary to add more<br>
details and results useful to the ITRF users.<br>
<br>
For any comment, question or specific request, please contact:<br>

<br>
Cordially<br>
