Dear All,

This is a short e-mail to inform you that we have (re)submitted our IGS
reprocessing products for the first 3 months of the year 2000.

Our original submission was done with our software not being fully complete.
Meanwhile we have finished most parts of our new software and redid the
reprocessing. This in order to have some better results before the upcoming
AGU meeting.

The main differences between these new products and the original ones are:

    * Integer ambiguity resolution
    * ERP estimation
    * Troposphere modelling with GPT and GMF.


Our new software is being used within the GGSP project (Galileo Geodetic
Service Provider) where it has demonstrated that the orbit quality obtained
is of the same level of precision as the orbit quality of the AIUB/CODE and
GFZ solutions. Our SINEX solutions are comparable as well although the level
of agreement is less good than in the orbits.

In any case we are convinced that these new products constitute a significant
improvement in quality compared to our original solutions. We are looking
forward to receiving feedback on these products.

Kind regards,
Florian Dilssner and Tim Springer
