Dear ITRF Users and Colleagues,

Three years after its release, the ITRS Center has initiated regular 
(yearly) updates of ITRF2020.

The IERS ITRS Center at IGN has the pleasure to announce to the 
community the
availability of the *ITRF2020-u2024* solution at the dedicated web site:

https://itrf.ign.fr/en/solutions/ITRF2020-u2024

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.

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).
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.

The ITRF2020-u2024 web site contains the most important results and 
information
regarding the ITRF2020-u2024 combination. It will be updated as 
necessary to add more
details and results useful to the ITRF users.

For any comment, question or specific request, please contact:
itrf at ign.fr

Cordially
Zuheir Altamimi
Head, IERS ITRS Center
