I have created a program (for inhouse use) to transform ITRF2020 epoch xxxx.xx positions (for example ITRF2020 2026.52 from RTX or OPUS) to NATREF2022 (ITRF2020 epoch 2020.00). However, I am...

To better describe the shape of the constantly deforming Earth’s surface, the ITRF2020 is provided as an augmented terrestrial reference frame that precisely models nonlinear station motions for both ...

I am trying using PROJ to perform some operations but in the middle I get stuck trying to change epoch for my coordinates For instance, to go from ITRF2020@2025.1 to ITRF2020@2000.0 I tried the following without success as it gives the same coordinates in output echo 4598595.07 359982.202 4390224.4| cs2cs +init=epsg:9988 +s_epoch=2025.1 +to +init=epsg:9988 +t_epoch=2000 I have the same problem with pyproj in python, I can manage to pass from ETRF2000@2015 to ITRF2000@2015 for instance but I didn't find an option to change the epoch in the same coordinate reference system as there is only one argument about epoch 'tt': from pyproj import Transformer X,Y,Z = 4598595.571, 359981.557, 4390223.928 #ETRF2000 geocentric 7930 to ITRF2000 geocentric 9988. output epoch is the same as input transformer = Transformer.from_crs(7930, 9988) X2, Y2, Z2, epoch2 =transformer.transform(xx=X, yy=Y, zz=Z, tt=2015) Can you help me as I'm struggling to find any example or people asking the same question?

**THIS IS A SCHEDULED EVENT Jul 30, 02:00 - 06:00 EDT** Jul 24, 07:55 EDT **Scheduled** - On July 30th, 2026, beginning at 02:00 EDT until 06:00 EDT, we will be performing routine physical station coordinate updates on the Hexagon SmartNet network, updating to ITRF2020 e2026.25. Updating the physical coordinates ensures the network accurately reflects the current station positions and reference frame realisation. This is a backend maintenance activity and will have no impact on customer experience and measurements after the change. We hope to keep service interruptions to a minimum, but please be advised customers may experience an outage of approximately 15-minutes disruption to service on each NTRIP caster as the roll-out is applied during this maintenance window. Purpose of Maintenance: - Update of physical coordinates for all Hexagon SmartNet sites The Hexagon SmartNet Team
