GPS/GNSS FTP Server Layout

Please note! By downloading files from UNAVCO's ftp server you are agreeing to abide by the UNAVCO Data Policy.

Please note! In order to avoid filenaming clashes due to non-unique 4-character IDs, campaign data are found only in the pub/pickup/campaigns area.

The following describes the UNAVCO GPS/GNSS FTP server layout for permanent station/continuous data, subject to the hierarchy:

     sub-hourly ( = nrt) supersedes highrate supersedes multi-hourly or hourly or daily

e.g. high-rate data that arrrives at UNAVCO as daily files or sub-hourly files or both would only be in our highrate directory. Regularly incoming sub-daily data is also combined into daily data, usually as RINEX.

For RINEX files created at UNAVCO, the standard observables are L1, L2, C1, P1, P2, S1, and S2 (if available in the raw data). For customized RINEX with other observables (e.g. doppler D1 and D2), please email archive-gpsunavco.org.
