Subject: [Sirgas-Mail] No.1600: igs08_1899.atx: Update including C017 and I007 From: Laura Sanchez This is a copy of [IGSMAIL-7308] igs08_1899.atx: Update including C017 and I007 Dear IGS colleagues! The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called ´igs08_1899.atx´. It contains the following changes: 1) The latest BeiDou-2 satellite (BeiDou IGSO 6) launched on 29 March 2016 has been added with conventional MGEX phase center offset values: C15 (C017) More information on the BeiDou constellation can be found at http://mgex.igs.org/IGS_MGEX_Status_BDS.html 2) The latest IRNSS satellite (IRNSS-1G) launched on 28 April 2016 has been added with ISRO-supplied phase center offset values: I07 (I007) More information on the IRNSS constellation can be found at http://mgex.igs.org/IGS_MGEX_Status_IRNS.html 3) According to Oliver Montenbruck, observation data with nadir angles above 15 degrees are available for the two Galileo satellites in elliptical orbits (E201, E202). Therefore, the maximum nadir angle has been increased from 15 to 16 degrees for these satellites. The updated antenna correction model is available at ftp://ftp.igs.org/pub/station/general/igs08_1899.atx or ftp://ftp.igs.org/pub/station/general/igs08.atx Many thanks to Simon Lutz, Zhiguo Deng and Peter Steigenberger for their help!
