== 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.

== 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)
