Subject: [SIR-Mail] No.736: igs08_1755.atx: Update including reactivated Block IIA satellite SVN32/PRN30 From: Laura Sanchez ******************************************************************************** SIR Electronic Mail 2013-08-28 08:43:39 UTC Message No. 736 ******************************************************************************** Dear IGS colleagues! The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called ´igs08_1755.atx´. It contains the following changes: 1) According to Richard Langley, Block IIA satellite SVN32 started transmitting signals as PRN30 on 22 August 2013. Therefore, the following satellite has been added to igs08.atx: G30 (G032) Sources: > SVN32 began transmitting signals as PRN30 at about 23:15:30 GPST on 22 > August (day 234) 2013 as monitored by a number of the tracking > stations participating in the International GNSS Service´s Multi-GNSS > Experiment. https://listserv.unb.ca/cgi-bin/wa?A2=CANSPACE;2e634e8c.1308 > NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2013049 NANU TYPE: GENERAL > *** GENERAL MESSAGE TO ALL GPS USERS *** > On approximately 22 AUG 2013 SVN32 will resume transmitting L-band > utilizing > PRN30. At L-band activation, SVN32/PRN30 will be unusable until further > notice. Additionally, no broadcast almanacs will include SVN32/PRN30 > until > further notice. http://cgls.uscg.mil/pipermail/nanu/2013-August/001520.html 2) A decommission date for the following satellite has been added: G30 (G049): 21 August 2013 The updated antenna correction model is available at ftp://igs.org/pub/station/general/igs08_1755.atx or ftp://igs.org/pub/station/general/igs08.atx Those who still didn´t switch to the GPS satellite antenna PCV extension can use the following model instead: ftp://igs.org/pub/station/general/igs08_1755_woPCVextension.atx This is the last parallel file! In the future, only models including the PCV extension will be provided.
