The UNAVCO Facility in Boulder, Colorado is the primary operational activity of UNAVCO and exists to support university and other research investigators in their use of geophysical sensor technology for Earth sciences research. The Facility performs this task in part by archiving GNSS/GPS data and data products for current and future applications.
Other data types that scientists use for Earth deformation studies are also held in the UNAVCO Archive collections. The Facility is funded under multi-year grants from the National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA).
Please read about the Archive for an overview of what we do, or see our FAQ for answers to questions about how the UNAVCO Facility Archive can serve you.

GPS Data Archive Interface Version 2 (DAI v2)
The Data Archive Interface Version 2 (DAI v2) is our next generation interface for search and access of UNAVCO's GPS data holdings. Use the DAI v2 to locate data of interest to you using a variety of filters (Metadata, Spatial, and Temporal). You can search for both permanent station and campaign monuments simultaneously, and download data associated with them.
| Web Application | Our new interface provides powerful and flexible search capability. [Flash Required] |
| Command-line clients | Download a suite of command line clients that utilize our web services for data search and access. [Java Required] |
