GPS/GNSS File Server Layout

Our data archive transitioned from FTP to HTTPS and as of March 30, 2023, requires registration and login for data access. For more information, see our notice about the transition.

The following describes the GPS/GNSS file server layout for permanent station/continuous data. By downloading files from GAGE's file server you are agreeing to abide by the GAGE Data Policy.

Please note:
  • In order to avoid filenaming clashes due to non-unique 4-character IDs, campaign data are found only in the /gnss/pickup/campaigns area by request via our Campaign Stations search tool. .
  • The file server files are subject to the hierarchy:

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

         e.g. high-rate data that arrrives at GAGE 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 GAGE, 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.
