Dear IGS colleagues,<br>
<br>
The Galileo IOV satellite antenna chamber calibrations have been
published in 2016 by the GSA (<a class="moz-txt-link-freetext"
href="https://www.gsc-europa.eu/support-to-developers/galileo-iov-satellite-metadata">https://www.gsc-europa.eu/support-to-developers/galileo-iov-satellite-metadata).</a><br>
At the IGS Workshop 2017 in Paris in the MGEX and in particular at
the Antenna working group splinter meeting we came to the conclusion
that the calibrated antenna patterns shall be included into the
official IGS ANTEX file.<br>
<br>
In addition to the regular IGS ANTEX file (igs14_wwww.atx), an extra
file containing the IOV chamber calibrations for Galileo IOV
satellites is made available and regularly updated
(igs14_wwww_iov.atx). The latest testing file is available on the
IGS ftp server (igs14_1967_iov.atx):<br>
<pre wrap="">
<a href="ftp://ftp.igs.org/pub/station/general/igs14_1967_iov.atx" class="">ftp://ftp.igs.org/pub/station/general/igs14_1967_iov.atx</a>
</pre>
<br>
During a transition time of one Month (until the 22 October 2017)
both ANTEX files will be maintained and published on the IGS ftp
server.<br>
As of 23 October 2017 the IOV pattern will be introduced in the
official IGS ANTEX file. <br>
<br>
If you have any comments about the new ANTEX file, please do not
hesitate to contact me.<br>
<br>
Many thanks to Oliver Montenbruck for preparing the IOV calibrations
in the ANTEX format.<br>
<br>
<br>
With best regards,<br>
Arturo Villiger <br>
on behalf of the IGS Antenna Working Group<br>
