GPS/GNSS Data Access Methods
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 |
Search Applications
We provide both graphical user interfaces and command line client applications to browse metadata and download data in the the GPS/GNSS Data Archive.
- DAI v2 [Requires Flash] NOTICE: Flash will be End of Life 2020-12-31. UNAVCO is working on a replacement.
- Java clients [Requires Java]
- DAI v1 - may be useful if you:
- Are having issues running Flash in your browser (required for the DAIv2), or installing Adobe AIR for its Download Cart.
- Need to search for specifics used in the acquisition of data archived at UNAVCO, e.g., monument style, receivers, or antennas searched via model or serial number.
- Need to search for campaign data by Principal Investigator (PI) or campaign name. Certain campaign data sets have no permanent monuments associated with the data files collected and these campaigns can only be searched with DAIv1.
FTP
GPS/GNSS data are available via our FTP server. See our FTP Server Layout for a guide to the server organization.
Web Services
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.
