<pre wrap="">Dear IGS colleagues,
The absolute IGS antenna correction file (igs14_wwww.atx) has been
updated. The new release is called 'igs14_2013.atx'. It contains
the following changes:
1) According to the Information Analytical Centre (IAC), GLONASS-M satellite
R856 (2018-053A) launched on 18 June 2018 was put into operation in slot 5.
According to the Center for Orbit Determination in Europe (CODE), R856 became
active on the 6 August 2018 (DOY 218). Note that the SVN number was assigned
according to an IGS Workshop recommendation (see IGSMAIL #7252) to 856
(changed from 756 to 856).
The following PRELIMINARY phase center offset (PCO) values were assigned:
PCO_X = -54.5 cm
PCO_Y = 0.0 cm
PCO_Z = 245.0 cm
2) The following decommission date has been added:
R05 (734): 05 October 2018
3) QZSS satellites order according to PRN number instead of SVN number
The updated antenna correction model is available at
