Who runs it? Who has access?

The Southern California Integrated GPS Network is operated by the Jet Propulsion Laboratory (JPL), the US Geological Survey (USGS), and the Scripps Institution of Oceanography (SIO) under the auspices of the Southern California Earthquake Center (SCEC). Other universities and agencies involved with the project include: the Massachusetts Institute of Technology (MIT), the University of California, Los Angeles (UCLA), Caltrans, Riverside County and the Riverside County Flood Control and Water Conservation District, Orange County, and Los Angeles County.

The network receives its major funding from the W.M. Keck Foundation, the National Aeronautics and Space Administration (NASA), the USGS, and the National Science Foundation (NSF).

Access to the SCIGN data is available to the public on-line from three data centers: one at JPL , one at Scripps , and one at the USGS , which shows "real-time" network results. The data are made available as soon as they can be downloaded from the site, processed, and then moved to the web. Daily coordinate solutions, periodic velocity solutions, and plots of time series showing the position of stations over time are made available very promptly to the scientific community as well as the public.

The SCIGN data policy states that the data can be used freely, as long as the users acknolwedge SCIGN and its funders as the source of the data. SCIGN is also coordinating with other networks (including ones in Northern California, Eastern Nevada, and Mexico) to provide even broader regional coverage of the entire Pacific-North American plate boundary. All of these networks share a similar data policy.
