ANTEX format description (antex11.txt): - An optional antenna-specific SINEX CODE was added for referencing the antenna model in SINEX files. - A remark concerning the position of COMMENT lines was added. Test set (pcv_abs_proposed11.tst): - The antenna offset in X-direction for the Block II and the Block IIA satellites was changed from 279.40 mm to 279.00 mm. - For the antenna TRM33429.20+GP absolute calibration results were added. - Those antennas whose phase center variations were converted from 'igs_01.pcv' and which do not possess calibration results for elevation angles below 10 degrees in the file 'igs_01.pcv' also do not possess absolute phase center variation values in the new file. - For each antenna the SINEX CODE (see above) 'IGS_2003' was inserted. The new ANTEX format description (version 1.1) and the new test set of antenna offsets and absolute phase center variations can be downloaded from the IGS CB information system at ftp://igscb.jpl.nasa.gov/igscb/station/general/pcv_proposed/ If there are any questions or further comments, please let us know.
