Welcome to the ITRF web site

The objective of this web site is to distribute the International Terrestrial Reference Frame (ITRF) products. ITRF94, ITRF96, ITRF97, ITRF2000, ITRF2005 and ITRF2008 solutions are available for download. It also contains the description and list of all the IERS stations.

A map server is available here to familiarize users about ITRF and help them to work with the products. The request for ITRF coordinates has also been simplified by the introduction of new web site tools.
