[IGSSTATION-6588] Properly Naming your Rinex 3 files

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 the RINEX 3 files are no longer appropriate.

In the enclosed 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, so continue to submit properly named 24 hour files, 1 hour 
files and 15 minute files only.

RINEX 3 file deliveries with the short names can now be discontinued to 
avoid confusion, once you have confirmed the new filenames are fine.

RINEX 3 files with short names will continue to be accepted for FOUR 
more months at least, 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 files, and 
you can see them there now, since the start of 2016.

Station RINEX 2 files with their regular names can be submitted in 
parallel to RINEX 3 longname files for as long as you want, as they may 
serve different communities, all RINEX data files will now be stored 
together for easier access and "discoverability" by all GNSS data users.

Thanks to everyone that has already switched, we have gone from 40 
stations to more than 85 stations using the correct names in a little 
over a month! ... still about 60 to go.
