The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called 'igs08_1730.atx'. It contains the following changes: 1) According to the Information-Analytical Centre, GLONASS-M satellite R743 was reactivated utilizing almanac slot 8. Therefore, the following satellite has been added to igs08.atx: R08 (R743) > According to the monitoring IAC, a planned maintenance with SC > Glonass-M #743 (orbital slot 8) successfully completed, the SC is used > for the intended purpose http://www.glonass-ianc.rsa.ru/en/content/news/?ELEMENT_ID=403 According to Stefan Schaer (IGSMAIL-6734) and Richard Langley (IGSMAIL-6737), the satellite already got activated on 22 February 2013. 2) According to IGSMAIL-6734 and IGSMAIL-6737, GLONASS-K1 satellite R801 was still active using the same almanac slot, when R743 was switched on. This is reflected by the following new file entry: R26 (R801) For more information please refer to the following two IGSMAILs: [IGSMAIL-6734] Irregular GLONASS constellation change (for R08) http://igscb.jpl.nasa.gov/pipermail/igsmail/2013/007924.html [IGSMAIL-6737] Two Active GLONASS Slot 8 Satellites Temporarily -- Potential Difficulties http://igscb.jpl.nasa.gov/pipermail/igsmail/2013/007927.html The updated antenna correction model is available at ftp://igs.org/pub/station/general/igs08_1730.atx or ftp://igs.org/pub/station/general/igs08.atx Thanks to Stefan and Richard for their help and sorry for the delay!
