The absolute IGS antenna correction file (igs08_wwww.atx) has been updated. The new release is called ´igs08_1748.atx´. It contains the following changes: 1) A single GLONASS-M satellite launched on 26 April 2013 was added with a preliminary z-offset value of 245 cm: R747 (R02) 2) A decommission date for the following satellite has been added: R728 (R02): 30 June 2013 Sources: NAGU 054-130701: > NOTICE ADVISORY TO GLONASS USERS (NAGU) 054-130701 > SUBJ: 02/-4 (728) UNUSABLE 01.07/0622 MT - UNFINISHED > 1.CONDITION: 02/-4 (728) UNUSABLE SINCE 01.07/0622 > MT (UTC+0300) UNTIL FURTHER NOTICE DUE TO MAINTENANCE NAGU 056-130704: > NOTICE ADVISORY TO GLONASS USERS (NAGU) 056-130704 > REF: 055-130702 > SUBJ: 02/-4 (747) PUT INTO OPERATION 04.07/1430 MT > 1.CONDITION: 02/-4 (747) PUT INTO OPERATION 04.07/1430 MT (UTC+0300) http://glonass-iac.ru/en/CUSGLONASS/index.php Richard Langley via Canspace: > GLONASS 747, a reserve satellite launched on 26 April 2013 and > fortuitously residing near orbital slot 2, took over the role of R02 > at about 12:10 UTC on 1 July according to MGEX tracking data. https://listserv.unb.ca/cgi-bin/wa?A2=CANSPACE;bdd2850a.1307 3) One additional robot calibration provided by NovAtel Inc. and performed by Geo++ GmbH: NOV703GGG.R2 NONE The updated antenna correction model is available at ftp://igs.org/pub/station/general/igs08_1748.atx or ftp://igs.org/pub/station/general/igs08.atx Those who still didn´t switch to the GPS satellite antenna PCV extension can use the following model: ftp://igs.org/pub/station/general/igs08_1748_woPCVextension.atx (Parallel files will only be provided until about end of July!)
