[IGSMAIL-7527] Preliminary IGS Antenna file including Galileo IOV chamber calibrated patterns

[Arturo Villiger]

Dear IGS colleagues,

The Galileo IOV satellite antenna chamber calibrations have been 
published in 2016 by the GSA 
(https://www.gsc-europa.eu/support-to-developers/galileo-iov-satellite-metadata).
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.

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):

ftp://ftp.igs.org/pub/station/general/igs14_1967_iov.atx


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.
As of 23 October 2017 the IOV pattern will be introduced in the official 
IGS ANTEX file.

If you have any comments about the new ANTEX file, please do not 
hesitate to contact me.

Many thanks to Oliver Montenbruck for preparing the IOV calibrations in 
the ANTEX format.


With best regards,
Arturo Villiger
on behalf of the IGS Antenna Working Group
