The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called ´igs08_1835.atx´. It contains the following changes: 1) According to NANU 2015010, Block IIA satellite SVN27 resumed transmitting L-band utilizing PRN26 on approximately 26 February 2015. According to the IGS tracking statistics as provided by CODE (ftp://ftp.unibe.ch/aiub/igsdata/odata_gnss_day.txt), SVN27/PRN26 was actually active on DOY 58 (27 February), 62, 64 and 69-72 in the meantime. Therefore, the following satellite has been added to igs08.atx: G26 (G027) Source: > NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2015010 NANU TYPE: GENERAL > *** GENERAL MESSAGE TO ALL GPS USERS *** > ON APPROXIMATELY 26 FEB 2015 SVN27 WILL RESUME TRANSMITTING L-BAND UTILIZING PRN26. AT L-BAND ACTIVATION, SVN27/PRN26 WILL BE UNUSABLE UNTIL FURTHER NOTICE. ADDITIONALLY, NO BROADCAST ALMANACS WILL INCLUDE SVN27/PRN26. FUTURE NANUS WILL INFORM USERS OF ANY CHANGES TO THE ABOVE-STATED STATUS. http://www.navcen.uscg.gov/?Do=gpsShowNanu&num=2015010 2) A decommission date for the following satellite has been added: G26 (G032): 24 February 2015 The updated antenna correction model is available at ftp://ftp.igs.org/pub/station/general/igs08_1835.atx or ftp://ftp.igs.org/pub/station/general/igs08.atx Thanks to Richard Langley for his help and sorry for the delay!
