<p>Dear colleagues,</p>
<p>It's our pleasure to announce a recent upgrade of our GFZ IGS
products. Starting with products for day 2021/138 we now provide
three-system rapid and ultra-rapid solutions including GPS,
GLONASS, and Galileo. Both processing lines rely on the official
IGb14 reference frame and the associated IGS14 ANTEX file
(<a class="moz-txt-link-freetext" href="https://files.igs.org/pub/station/general/igs14.atx">https://files.igs.org/pub/station/general/igs14.atx</a>).<br>
</p>
The products are available via the GFZ Information System and Data
Center (<a class="moz-txt-link-freetext" href="https://isdc.gfz-potsdam.de/gnss-products/">https://isdc.gfz-potsdam.de/gnss-products/</a>). For further
details you might see the respective DOIs:<br>

<p>The GFZ final products will remain GPS and GLONASS only to avoid
discontinuities in the coordinate time series. We will update our
final solution when switching to the next ITRF realization. <br>
