USGS GPS Data
Real-time GPS Data
The U.S. Geological Survey (USGS) Earthquake Science Center operates a network of eight real-time GPS stations in the San Francisco Bay area. Each station transmits 1-Hz data to a processing center located on the USGS main campus in Menlo Park. A suite of web-based applications monitor on a continuous basis the network's operational status , data streaming performance and deformation within the network.

Data Access
Receiver data, both raw and RINEX 24-hour files, and site information are available from the Northern California Earthquake Data Center using FTP. The raw and RINEX data files are in day-of-year directories.
Survey-Mode GPS Data
An effort is underway to catalog and distribute survey-mode GPS data collected in the western United States, primarily in northern California. This includes a dataset of over 6000 occupations collected in 1992-present by the USGS/Menlo Park in California, Oregon, Washington, Nevada, Utah, Idaho, and Alaska. Currently, we have made approximately 98% of these data files available, after verifying the consistency of the raw, RINEX, and scanned log sheets, and defining monument identifiers that are unique within the NCEDC system. Similar efforts are planned for other high-precision GPS datasets that have been collected by NGS, Caltrans, and other university, government, and commercial agencies.
