The International Terrestrial Reference Frame (ITRF)

The International Terrestrial Reference Frame (ITRF) is a set of points with their 3-dimensional cartesian coordinates which realize an ideal reference system, the International Terrestrial Reference System (ITRS), as defined by the IUGG resolution No. 2 adopted in Vienna, 1991.

Contents  
- cartesian stations coordinates and velocities
- site catalogue
- DOMES identification numbers (see "Documentation")
- local ties (see "Documentation")
-  realizations: ITRF89, ITRF90, ITRF91, ITRF92, ITRF93, ITRF94, ITRF95, ITRF96, ITRF97, ITRF2000, ITRF2005 (in preparation)
 
Accuracy   Uncertainties are given in the solutions.
