The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called ´igs08_1887.atx´. It contains the following changes: 1) According to the Information Analytical Centre (IAC), GLONASS-M satellite R736 replaced GLONASS-M satellite R738 in almanac slot 16. Therefore, the following satellite has been added: R16 (R736) According to the Center for Orbit Determination in Europe (CODE), R736 is already active since 9 March 2016 (DOY 69). sources: > | 736 | 2464 | 2/16 | -1 | 02.09.2010 | 01.10.2010 | unusable | 14.02.2016 | https://www.glonass-iac.ru/en/CUSGLONASS/index.php > 16.02.2016 > According to GLONASS System Control Centre SC Glonass-M #736 (orbital slot 9) will be set unusable from 17:09 16.02.16 (MT) till 17:22 09.03.16 (MT) for the works on moving SC to orbital slot 16 https://www.glonass-iac.ru/en/content/news/?ELEMENT_ID=1561 2) A decommission date for the following satellite has been added: R16 (R738): 14 February 2016 NAGU message 012-160219: > NOTICE ADVISORY TO GLONASS USERS (NAGU) 012-160219 > SUBJ: 16/-1 (738) UNDER CHECK BY THE SPC SINCE 14.02/1045 MT > 1.CONDITION: 16/-1 (738) UNDER CHECK BY THE SPC > SINCE 14.02/1045 MT (UTC+0300) https://www.glonass-iac.ru/en/CUSGLONASS/index.php 3) One robot calibration provided by Trimble Navigation Ltd. has been added: TRMR2 NONE The updated antenna correction model is available at ftp://ftp.igs.org/pub/station/general/igs08_1887.atx or ftp://ftp.igs.org/pub/station/general/igs08.atx Many thanks to Richard Langley and Stefan Schaer for their help!
