After an inspection of the NAIN antenna this week, we discovered an unfortunate error in the antenna type reported in the site log and RINEX files for this station since the beginning of operation in late 2002. Until now, the log & RINEX files had incorrectly reported an antenna type of ASH701945C_M NONE. It should have been ASH701945D_M NONE. The site log has been corrected and submitted to the Central Bureau (corrected section is copied below). Starting today RINEX files will include the correct antenna type. We will also begin correcting and resubmitting all historic RINEX files. I will advise when all the corrected files have been posted to the IGS archives. We apologize for any problems this might cause.
