The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called 'igs08_1808.atx'. It contains the following changes: 1) According to NANU 2014069, Block IIA satellite SVN35 resumes transmitting L-band utilizing PRN03 on approximately 5 September 2014. Therefore, the following satellite has been added to igs08.atx: G03 (G035) Source: > NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2014069 NANU TYPE: GENERAL > *** GENERAL MESSAGE TO ALL GPS USERS *** > ON APPROXIMATELY 05 SEP 2014 SVN35 WILL RESUME TRANSMITTING L-BAND UTILIZING PRN03. AT L-BAND ACTIVATION, SVN35/PRN03 WILL BE UNUSABLE UNTIL FURTHER NOTICE. ADDITIONALLY, NO BROADCAST ALMANACS WILL INCLUDE SVN35/PRN03 UNTIL FURTHER NOTICE. http://www.navcen.uscg.gov/?Do=gpsShowNanu&num=2014069 2) A decommission date for the following satellite has been added: G03 (G033): 18 August 2014 Although officially removed from the GPS constellation on 2 August 2014 (see NANU 2014063), SVN33 didn't stop signal transmission before 18 August 2014 according to the IGS tracking statistics provided by CODE (ftp://ftp.unibe.ch/aiub/igsdata/odata_gnss_day.txt). The updated antenna correction model is available at ftp://ftp.igs.org/pub/station/general/igs08_1808.atx or ftp://ftp.igs.org/pub/station/general/igs08.atx Please be aware that the latter link changed! Thanks to Richard Langley for his help! With best regards, Ralf Schmid on behalf of the IGS Antenna Working Group
