[IGS-Equipment-Files] igs08_1880.atx: Update including 3 additional receiver antenna calibrations

[Ralf Schmid]

Dear IGS colleagues!

The absolute IGS antenna correction file (igs08_wwww.atx) has been 
updated. The new release is called 'igs08_1880.atx'. Receiver antenna 
calibrations for three additional antenna types provided by Topcon 
Positioning Systems Inc. and performed by Geo++ GmbH have been added:

TPSCR.G5        NONE
TPSCR.G5C       NONE
TPSCR.G5C       TPSH

The updated antenna correction model is available at
ftp://ftp.igs.org/pub/station/general/igs08_1880.atx
or
ftp://ftp.igs.org/pub/station/general/igs08.atx

Those who don't cope with the MGEX extension can use the following model 
instead:

Many thanks to Topcon Positioning Systems Inc. for providing phase 
center corrections to the IGS!

With best regards,
Ralf Schmid
