To all station data providers currently providing Rinex 3 files as part of the IGS network. Please at your earliest convenience implement the correct naming scheme for your Rinex 3 files as the old Rinex 2 names for Rinex 3 files are no longer appropriate.
Enclosed in the pdf is a set of recommendations that you may findEnclosed in the pdf is a set of recommendations that you may find useful, but many different organizations have implemented their own renaming methods, and some vendors already allow correct naming of Rinex 3 files but clearly not all so some action from Station Operators is needed.
The Rinex 3 format clearly defines the new naming structure: http://bit.ly/1YaodnI
To find your “IGS station long name” go to http://igs.org/network click on “options” , and in the first column “Site” select the checkbox “Long Name” to show the name expected by the IGS for all stations. If you disagree with the country code in the Long Name assignment please inform us quickly so as to avoid confusion, for now all stations have “00” for receiver and antenna.
Again this affects only Rinex 3 Station Data Providers (previously “MGEX stations”, now called “multi-GNSS stations”) .
The data files acceptable for the IGS continues to be; Daily (30sec), Hourly (30 sec) and Highrate (1sec) 15 min files. The “expected” name is assumed, if you have doubts please let us know. If you base your long name on the current filenames you are delivering as part of “mgex” then the name will be fine. Rinex 3 filenames are very flexible for the benefit of the entire GNSS community, but the IGS will not be taking advantage of that full flexibility.
RINEX 3 file deliveries with the old names can be discontinued if you want, once you have implemented the new filenames, but they will continue to be accepted in parallel for six months if you want to continue to submit them and will be stored as always in the /mgex campaign directories in the different IGS Data Centers. RINEX 3 files with the correct long names will be merged into the regular IGS GNSS data repository together with the Rinex 2 data, and you can see them in there since the start of 2016.
Rinex 2 files with their standard names can be submitted in parallel to Rinex 3 files for as long as you want, as they may serve different communities, all RINEX files will now be stored together for easier access and “discoverability” by all GNSS data users.
