Welcome to the Earthdata Forum! Here, the scientific user community and subject matter experts from NASA Distributed Active Archive Centers (DAACs), and other contributors, discuss research needs, data, and data applications.
The CDDIS is a separate archive from BKG, so we are not responsible for their data. The BKG data center has been experiencing an outage since Mar. 25. The CDDIS does not archive BRDC*GN.rnx files. We only have the mixed navigation files with name format, BRDC*MN.rnx. The BRDC files available at the CDDIS can be found here. https://cddis.nasa.gov/archive/gnss/data/daily/2022/brdc/
