Dear colleagues
The release of the igs14_2056.atx has a format issue (an additional blank) in the line of the Beidou PCO values ('NORTH / EAST / UP'). I am generating a corrected version which will re-uploaded as soon as possible to the IGS ftp server.
Best regards,
Arturo

Subject: [IGSMAIL-7782] igs14_2056: Update including Beidou-3S and Beidou-3 satellites
Dear IGS colleagues,
The absolute IGS antenna correction file (igs14_wwww.atx) has been updated. The new release is called 'igs14_2056.atx'. It contains the following changes:
1) Oliver Montenbruck from DLR made an effort and collected all available information on the Beidou PCO values and proposed an update of the currently used values (including PCO values for satellites which are not yen in the IGS ANTEX file). After sending around the proposed values in the IGS Antenna Working Group the block specific PCO values are now added to the IGS ANTEX file:
PCO Values:
Beidou-2 satellites (average values from various publications):
BEIDOU-2G

[m] [m] [m]
B1: 0.58 0.00 3.50
B2: 0.58 0.00 3.50

The SVN / PRN assignment are made according to the satellite metadata information file provided by the IGS-MGEX Working group (http://mgex.igs.org/IGS_MGEX_Metadata.php).
Satellite meta data SINEX file: http://mgex.igs.org/igs_metadata_2046.snx.
2) Two additional antenna type calibration has been added that were performed by Geo++ GmbH:
- Two robot calibration provided by Tallysman Wireless has been added:
TWIVC6150 NONE
TWIVC6150 SCIS
The updated antenna correction model is available at
ftp://ftp.igs.org/pub/station/general/igs14_2056.atx
or
