The absolute IGS antenna correction file (igs05_wwww.atx) has been updated. The new release is called 'igs05_1581.atx'. It contains the following changes: 1) Spared GLONASS-M satellite R714 (active in orbital slot 23 until 18 March 2010) was reactivated as R06. So, the following file entry was added: R06 (R714): 28 April 2010 On Wednesday, April 28 (DOY 118), first IGS stations (IRKJ, LHAZ, REYK) started tracking R714 as R06: ftp://ftp.unibe.ch/aiub/igsdata/y2010/odata_glonass_d118.txt On Thursday, April 29, also the IAC confirmed the reactivation of R714: > 29.04.2010 Today the works on investigation of a potential for using the spared GLONASS-M satellites in operation mode have been starting on GLONASS #714 (launched on 25.12.2005). The expected date of finishing works is 07.05.2010 http://www.glonass-iac.ru/pls/htmldb/f?p=202:1:2419780714980575 Unfortunately, no announcement was made before. Thanks to Stefan Schaer and the CODE AC team for pointing to that reactivation! 2) A 'decommission' date for the following satellite was added: R06 (R701): 27 April 2010 The updated antenna correction model is available at ftp://igs.org/pub/station/general/igs05_1581.atx or ftp://igs.org/pub/station/general/igs05.atx Information on the upcoming switch from igs05.atx to igs08.atx may be found at http://www.iapg.bv.tum.de/mediadb/117723/117724/Vortrag_AGU09_schmid.pdf With best regards, Ralf Schmid and Robert Khachikyan on behalf of the IGS Antenna Working Group
