Subject: Improvement of PZ90/ITRF transformation


Dear Colleagues,

One of the IGEX-98 workshop (Nashville) conclusion is that
an improved PZ90/ITRF transformation is really needed.

We are planing to improve our study concerning PZ90/ITRF 
transformation, initiated at the time of IGEX-98 Workshop.

In this respect, we kindly ask all IGEX Analysis Centers
to contribute to this study by sending us sets of station 
coordinates processed with GLONASS broadcast ephemerides.

We accept any such data, preferably in SINEX format, together
with a report describing the computation.

E-mail contact: itrf@ensg.ign.fr

Best Regards
Claude Boucher and Zuheir Altamimi
