Starting with data from 2016, all RINEX V3 data using the RINEX V3 filenaming convention will now be made available in the operational Global Navigation Satellite Systems (GNSS) data archives at Crustal Dynamics Data Information System (CDDIS):
This change has been implemented at the International GNSS Service (IGS) data centers in accordance with the IGS RINEX 3 transition plan (http://bit.ly/1Md7VhU). This update to the CDDIS archive is the next logical step to continue to integrate those stations supporting the IGS MGEX and all their data files into the regular IGS structures and make accessing all RINEX data easier and more transparent for the user community. The RINEX V3.03 format documentation is available at http://bit.ly/1YaodnI.
The CDDIS will continue to archive RINEX V3 files supplied with short names (8.3 format) in the MGEX campaign directories (ftp://cddis.gsfc.nasa.gov/gnss/data/campaign/mgex). Please contact the CDDIS staff if you have any questions or problems.
