We are pleased to announce the operational status of our new CDDIS server,
cddis.gsfc.nasa.gov.  All GPS and GLONASS data and products are now
available through this new server in an updated directory structure.  We
ask that you begin your efforts to transition your data access software to
utilize the new system.  In the meantime, we will maintain the archives
on the old CDDIS server, cddisa.gsfc.nasa.gov, for some months yet to
allow our user community to make the necessary changes.

The main directories of the new GPS and GLONASS archive are as follows:
 /campaign                   GPS data from selected campaigns

 /daily/YYYY/DDD/YYd         Observation files for year YYYY and day DDD
                             (Hatanaka format)
                 /YYm        Met files for year YYYY and day DDD
                 /YYn        Navigation files for year YYYY and day DDD
                 /YYo        Observation files for year YYYY and day DDD
                 /YYs        Summary files for year YYYY and day DDD
                             (teqc output)
 /hourly/YYYY/DDD/HH         Hourly RINEX GPS files for year YYYY, day DDD,
                             and hour HH; observation (Hatanaka format),
                             navigation and met data

 /high-rate/YYYY/DDD/YYd/HH  Observation files for day YYDDD and hour HH
                             (Hatanaka format)
                    /YYm/HH  Met files for day YYDDD and hour HH
                    /YYn/HH  Navigation files for day YYDDD and hour HH

 /satellite/SATNAME/YYYY/DDD GPS data from on-board GPS receivers for
                             satellite SATNAME for year YYYY and day DDD

                    /YYYY         Yearly GPS troposphere products for year
                                  YYYY 
                    /nrt/WWWW     Near real-time GPS troposphere products
                                  for GPS week WWWW
               /trop_new/YYYY/DDD New IGS troposphere product for year
                                  YYYY and day DDD
               /WWWW              Weekly GPS precise orbits, etc. for GPS
                                  week WWWW 

In addition to the data archive, the CDDIS website has been redesigned
and is not operational on http://cddis.gsfc.nasa.gov.  A more detailed 
structure diagram for the new archive can be found on this website at
http://cddis.gsfc.nasa.gov/ftpgpsstruct.html.

We welcome your comments on the new server and website.

Regards,
Carey.
