We are thankful to the station operators and the respective agencies that have contributed their data to the IGS network. They will be missed.
A complete list of dormant stations is available at: http://igs.org/network/dormant.html
In conjunction we are working on a proposed list of stations that have replaced the decommissioned stations. More to follow...

Dear IGS colleagues!
The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called 'igs08_1639.atx'. It contains the following changes:
1) A decommission date for the following satellite has been added:
G01 (G049): 6 May 2011
NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2011039 NANU TYPE: GENERAL *** GENERAL MESSAGE TO ALL GPS USERS *** GPS satellite SVN49 (PRN01) was decommissioned from active service on JDay 126 (06 May 2011). PRN01 is available for future satellite service. http://cgls.uscg.mil/pipermail/nanu/2011-May/001307.html
2) According to 'NANU 2011043' the following satellite has been added:
NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2011043 NANU TYPE: GENERAL *** GENERAL MESSAGE TO ALL GPS USERS *** On approximately 1 June 2011, SVN35 will resume transmitting L-band utilizing PRN01. At L-band activation, SVN35/PRN01 will be unusable until further notice. Additionally, no broadcast almanacs will include SVN35/PRN01. Future NANUs will inform users of any changes to the above-stated status. http://cgls.uscg.mil/pipermail/nanu/2011-May/001314.html
The updated antenna correction model is available at ftp://igs.org/pub/station/general/igs08_1639.atx or ftp://igs.org/pub/station/general/igs08.atx

Dear IGS Colleagues:
This is to announce that starting on May 24, 2011 (1637/2), NRCan has switched to the Bernese 5.0 software for its Rapid product estimation. NRCan is now providing orbits and 30 sec clocks for both GPS and GLONASS
satellites. The new products are sent to the ACC for combination in the IGS Rapid solution (IGR). Please note that NRCan Ultra Rapid solution (GPS only/Bernese 5.0) and NRCan Final solution (GPS only/GIPSY) remained unchanged.
