This has been allowed in the RINEX specification (ftp://igscb.jpl.nasa.gov/pub/data/format/rinex210.txt) for some time, but the GLONASS data has been kept in separate directories. Also, when the IGLOS Pilot Project begins in earnest, the IGLOS sites will become bona fide IGS sites and as such, site logs for GLONASS stations will be moved into the IGS site log directory at ftp://igscb.jpl.nasa.gov/pub/station/log/. GLONASS stations will also appear in the IGS SINEX template ftp://igscb.jpl.nasa.gov/pub/station/general/igs.snx when that happens. The Central Bureau is currently working on a modification of the IGS site log form to account for GLONASS (or other) tracking stations. The IGEX and potential IGLOS stations have been using a tentatively modified IGS site log form. There is no certain date for implementation at this time, but we felt a reminder at this time would head off any potential problems. IGS users are advised to ensure that their software systems will behave as desired in terms of GPS/GLONASS RINEX data, site logs, and SINEX template by January 2001 to be ready for the change. Most especially, the processing programs should either properly process GLONASS observations or merely skip them.
