== toward a better description ==
As the encyclopedia is intended for a general audience, a more general description of the ITRS and ITRF would be useful. A description of the x,y,z Cartesian coordinates of points on the Earth's surface and the methods of conversion of these coordinates to conventional latitude and longitude would add great clarity. Perhaps an image of the Earth's globe should be included.
Granted, the IERS webpage is not clear about this but the IERS products are not intended for a general audience.

== Article should mention earlier versions ==
The early versions of the ITRS were know as BIS84 etc. May be worthwhile mentioning this. See https://www.iers.org/SharedDocs/Publikationen/EN/IERS/Publications/tn/TechnNote04/tn04_01.pdf?__blob=publicationFile&v=1 for details.

:Yes, BTS84 is an early TRF using using station coordinates. <samp>+[[User:Mwtoews|<span style="color: #008000;">m</span>]][[User talk:Mwtoews|<span style="color: #6B3FA0;">t</span>]]</samp> 22:10, 5 September 2019 (UTC)
== Latest ITRF ==
There is at least ITRF 2014.[[Special:Contributions/150.227.15.253|150.227.15.253]] ([[User talk:150.227.15.253|talk]]) 09:25, 19 October 2021 (UTC)
Oops, 2014 was included further down. It was the sentence "The difference between the latest WGS 84 and the latest ITRF (as of 2006) is only a few centimeters." that triggered my comment. More information on the relation between WGS84 and ITRF would be desirable![[Special:Contributions/150.227.15.253|150.227.15.253]] ([[User talk:150.227.15.253|talk]]) 09:30, 19 October 2021 (UTC)
