Dear colleagues!

If there are any manufacturers that are not subscribed to
igs-equipment-files email exploder, please do so. We announce updates
to IGS Equipment Files there that may not be necessarily announced here.

The absolute IGS antenna correction file (igs05_wwww.atx) has been
updated. The new release is called 'igs05_1521.atx'. It contains the
following changes:

1) Two additional robot calibrations provided by Trimble Terrasat GmbH:

TRM59800.00     NONE
TRM59800.00     SCIS

2) Two additional robot calibrations provided by Geo++ GmbH:

ASH701945C_M    PFAN
LEIAT504        OLGA

The latter two antenna types were formerly used at the Austrian EPN 
stations PFAN and TRFB, but not in use within the IGS network so far:

Many thanks to Trimble Terrasat as well as Geo++ for making available 
these four type mean calibrations!
