The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called 'igs08_1927.atx'. It contains the following changes: 1) According to the Information and Analysis Center for Positioning, Navigation and Timing (IAC), GLONASS-M satellite R723 replaced GLONASS-M satellite R737 in almanac slot 12. Therefore, the following satellite has been added: R12 (R723) sources: > 12 2 -1 723 25.12.07 107.8 - - 10:08 15.12.16 Commissioning Phase https://www.glonass-iac.ru/en/GLONASS/ > According to GLONASS System Control Centre, the SC Glonass-M #723 at 00:00 MT (UTC+3) 15.12.2016 in commissioning phase https://www.glonass-iac.ru/en/content/news/?ELEMENT_ID=1799 2) According to the IGS tracking statistics provided by CODE (ftp://ftp.unibe.ch/aiub/igsdata/odata_gnss_day.txt), R737 stopped signal transmission on 21 November 2016 (DOY 326). Therefore, a decommission date for the following satellite has been added: R12 (R737): 21 November 2016 source: > According to GLONASS System Control Centre, the SC Glonass-M #737 at 00:00 MT (UTC+3) 15.12.2016 under check by the Satellite Prime Contractor https://www.glonass-iac.ru/en/content/news/?ELEMENT_ID=1798 3) The start date of the reactivated Block IIA satellite G034/G04 was corrected: 7 December 2016 --> 9 December 2016 The updated antenna correction model is available at ftp://ftp.igs.org/pub/station/general/igs08_1927.atx or ftp://ftp.igs.org/pub/station/general/igs08.atx With best regards,
