Subject: [SIR-Mail] No.836: igs08_1771.atx: Update including reactivated Block IIR-M satellite SVN49/PRN30 From: Laura Sanchez Estimados Amigos: El IGS acaba de anunciar una nueva actualización del archivo con los PCV. Si bien no hay cambios en las antenas ”terrestres”, es importante que actualicemos este archivo en nuestro protocolo de cálculo, porque hay cambios en las antenas satelitales, los cuales son tan importantes como los de las antenas terrestres; más aún si estamos trabajando con los nevos estándares.

It contains the following changes: 1) According to NANU 2013080, Block IIR-M satellite SVN49 resumed transmitting L-band utilizing PRN30 on 19 December 2013. Therefore, the following satellite has been added to igs08.atx: G30 (G049) Source: > NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2013080 NANU TYPE: GENERAL > *** GENERAL MESSAGE TO ALL GPS USERS *** ON APPROXIMATELY 19 DEC 2013, SVN49 WILL RESUME TRANSMITTING L-BAND UTILIZING PRN30. AT L-BAND ACTIVATION, SVN49/PRN30 WILL BE UNUSABLE UNTIL FURTHER NOTICE. ADDITIONALLY, NO BROADCAST ALMANACS WILL INCLUDE SVN49/PRN30 UNTIL FURTHER NOTICE. http://www.navcen.uscg.gov/?Do=gpsShowNanu&num13080 2) A decommission date for the following satellite has been added: G30 (G027): 17 December 2013 According to the IGS tracking statistics as provided by CODE, G30 data is not available for DOY 352 (18 December 2013): ftp://ftp.unibe.ch/aiub/igsdata/odata_gnss_day.txt The updated antenna correction model is available at ftp://igs.org/pub/station/general/igs08_1771.atx or ftp://igs.org/pub/station/general/igs08.atx Thanks to Richard Langley for his help!
