Status of the art on geodetic reference frame: ITRF2000 and the next ITRS realizations
Abstract
In this paper is presented a brief historic of the ITRS realizations, giving details
of the most recent, ITRF2000, as well as the parameters involved in the
transformation among them. Some deficiencies of ITRF2000 are presented
together with descriptions of how should be it in the future. Therefore, the status
of Geodetic Reference System will be presented. Quality control analysis for some of the stations situated in the South American continent is presented in
terms of precision and discrepancies with respect to other frames. Finally, it was
emphasized about the care that one should take when using coordinates of
stations located in regions subjected to seismic shock and earthquakes.
