Dear IGS Colleagues,

Please note that an update of the IGS antenna calibration file provided
by Ralf Schmid is now posted at:
ftp://igscb.jpl.nasa.gov/pub/station/general/igs05_1467.atx
And as always the static link (below) always points to the latest .atx file:
ftp://igscb.jpl.nasa.gov/pub/station/general/igs05.atx 
<ftp://igscb.jpl.nasa.gov/pub/station/general/igs05_1467.atx>

Summary to the changes are as follows:

1) The latest GLONASS-M satellites launched on 25 December 2007 have 
been added with preliminary z-offset values of 230.0 cm:

R09 (R722)
R11 (R723)
R13 (R721)

2) According to the following sources R798 changed its orbital slot 
number from 19 to 22 in October/November 2007:

http://russianforces.org/blog/2007/12/second_glonass_launch_of_2007.shtml

In order to account for that, a "decommission date" for

R22 (R791)

has been added. Besides, there is a new file entry for

R22 (R798)

The date of changeover has been chosen to be the launch date of R19 
(R720), i.e. 26 October 2007. Thus, there is the same "decommission 
date" for R19 (R798) and R22 (R791).
