Dear IGS community,

Please note that starting this week the RINEX 3 files arriving at
IGS Data Centers with longnames will be merged into the regular
RINEX repository.

This step is taken in accordance with the Rinex 3 transition plan
(http://bit.ly/1Md7VhU) and after a lot of work of the Data Center WG
Chair and its members; thanks guys!  We need this as the next logical 
small step to
continue to integrate the stations and all the data files into the
regular IGS structures. The MGEX has proven the underlying concepts and
the Rinex 3 format (http://bit.ly/1YaodnI) is now consolidated.

Data Centers will continue to store Rinex 3 files supplied with short
names (8.3) in the mgex campaign directory as usual (or their equivalent).
The IC and NC will start to contact station operators to encourage them
to submit Rinex 3 files with longnames and to continue short name 
submissions in
parallel for six months as an adjustment period. It is the view of the
IGS NC, IC, MGEX, DC and GB that all station GNSS data files regardless
of the format should be stored together to make accessing all the RINEX 
data
easier and more transparent.

The longname Rinex 3 files are part of the IGS network of stations
(multi-GNSS stations) and were formerly stored exclusively in the
campaign/mgex/YYYY/DDD/crx directory; you can see current examples here;

ftp://cddis.nasa.gov/gps/data/campaign/mgex/daily/rinex3/2015/325/crx/

now these files will start to be merged into the regular GNSS data 
directories.

Please be aware of this change for your data download methods.  Over the 
year
expect more and more station files in RINEX 3 longfilenames.  It is 
expected that station
owners which already do so will continue to submit Rinex 2 files with 
8.3 filenames
and Rinex 3 files with longnames.

Best regards,
Nacho
