<br><font size=2 face="sans-serif">Dear Colleagues,</font>
<br>
<br><font size=2 face="sans-serif">With this e-mail we are happy to announce
that the reprocessing results from ESA/ESOC are now publicly available
at the CDDIS. The main purpose of this reprocessing is that it will contribute
to the realisation of the next International Terrestrial Reference Frame
Realisation, the ITRF2013. However, all the products should be an improvement
compared to the currently available products as all was processed with
the latest models and in a completely homogeneous manner.</font>
<br>
<br><font size=2 face="sans-serif">Our reprocessing results covers the
time preiod start at 1.1.1995 and finishing at 28.12.2013. This is a grand
total of 6937 days, 991 weeks. Products submitted are daily SP3, CLK, and
SNX files and weekly ERP files. Note that our submitted clock solutions
have a sampling rate of 5 minutes. However, for the full time span we do
have clock solutions with 30 seconds sampling available. But those are
available on special request only. </font>
<br>
<br><font size=2 face="sans-serif">Until the end of 2008 the solution are
based on processing only the GPS data using a network of 150 stations.
>From 2009 GPS and GLONASS data is processed. Due to the increased number
of satellite the number of stations was reduced from 150 to 110 for the
combined GPS+GLONASS solutions.</font>
