Dear colleagues,

several suggestions and comments from some of you led to some small 
modifications of the ANTEX format. The new version 1.2 allows for the 
serial number of the reference antenna as well as for the calibration 
method "ROBOT". Besides, the use of ".atx" as file extension is recommended.

Following the recommendation of the last IGS Workshop in 
Bern/Switzerland, that ANTEX should become the official IGS format, the 
file format description "antex12.txt" can now be found at 
"ftp://igscb.jpl.nasa.gov/igscb/station/general";. At the same place, a 
file named "igs_01.atx" is located that contains the relative receiver 
antenna phase center offsets and variations given in the file 
"igs_01.pcv" (Previously valid old antenna names have not been included 
anymore!). Moreover, "relative" satellite antenna phase center offsets 
and variations (zero patterns) have been added.

For those who are interested, a test set of absolute receiver and 
satellite antenna phase center corrections can still be found at 
"ftp://igscb.jpl.nasa.gov/igscb/station/general/pcv_proposed";.

With best regards,
                        Ralf Schmid (schmid @ bv.tum.de)
