UNAVCO archives and distributes GPS/GNSS data in a variety of product levels, formats and access methods. Product levels distinguish between raw data (Level 0), pre-processed data (Level 1), and post-processed/derived (Level 2) data products.
GPS/GNSS Data Products | Access Method / Product Format | |||||
---|---|---|---|---|---|---|
Data Product Level | Description | Generation Frequency | Creator | FTP | Web Graphical Interface | Web Service |
Level 1 | Standard rate data (15-sec) | Daily, varies | UNAVCO | RINEX | RINEX | n/a |
High rate data (1-, 2-, 5-sps) | Varies | UNAVCO | RINEX | RINEX | n/a | |
Survey-mode (campaign) data | Daily, varies | UNAVCO | n/a | RINEX | n/a | |
Level 2 | Position solution time series | Daily | MIT | ASCII, CSV | ASCII, CSV | ASCII, CSV |
Velocity solutions | Monthly | MIT | ASCII | ASCII | ASCII, CSV | |
Position offsets (e.g. coseismic) | Varies | MIT | ASCII | n/a | n/a | |
Tropospheric parameter estimates | Daily | CWU | ASCII | n/a | n/a | |
Position solution QA parameters | Daily, varies | UNR | ASCII | ASCII | n/a | |
Position solutions (loose) | Daily | CWU | SINEX | SINEX | n/a | |
Position solutions (constrained) | Daily | MIT | SINEX | SINEX | n/a |
We provide both graphical user interfaces and command line client applications to browse metadata and download data in the the GPS/GNSS Data Archive.
GPS/GNSS data are available via our FTP server. See our FTP Server Layout for a guide to the server organization.
See our Web Services for RESTful Web Service access to data (e.g. position time series for stations analyzed by GAGE and the University of Nevada Reno Geodetic Laboratory, meteorological data from surface sensors colocated with GPS/GNSS stations) and selected metadata.
