The absolute IGS antenna correction file (igs05_wwww.atx) has been updated. The new release is called 'igs05_1502.atx'. It contains the following changes: 1) According to 'NANU 2008130' a decommission date for the following satellite has been added: G01 (G032): 16 October 2008 NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2008130 NANU TYPE: GENERAL *** GENERAL MESSAGE TO ALL GPS USERS *** ON 16 OCT 2008, SVN32 DISCONTINUED TRANSMITTING L-BAND. PRN01 IS AVAILABLE FOR FUTURE SATELLITE SERVICE. 2) According to 'NANU 2008131' the following satellite has been added: G01 (G037) NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2008131 NANU TYPE: GENERAL *** GENERAL MESSAGE TO ALL GPS USERS *** ON APPROXIMATELY 23 OCT 2008, SVN37 WILL RESUME TRANSMITTING L-BAND UTILIZING PRN01. AT L-BAND ACTIVATION, SVN37/PRN01 WILL BE UNUSABLE UNTIL FURTHER NOTICE. ADDITIONALLY, NO BROADCAST ALMANACS WILL INCLUDE SVN37/PRN01. FUTURE NANUS WILL NOTIFY USERS OF ANY CHANGES TO THE ABOVE-STATED STATUS. 3) The launch date of G060 has been corrected: 22 June 2004 --> 23 June 2004 4) The COSPAR IDs of R718 and R720 have been corrected: R718: 2007-052A --> 2007-052C R720: 2007-052C --> 2007-052A 5) A comment as regards the type of R711 has been added.
