Welcome to SCIGN

The Southern California Integrated GPS Network (SCIGN) has accomplished its goal of completing a state-of-the-art array of 250 continuously-operating GPS stations. Therefore the SCIGN collaboration ( US Geological Survey, Scripps Institution of Oceanography, Jet Propulsion Laboratory ) under the Southern California Earthquake Center has been disbanded.
SCIGN stations are now operated by the following agencies:

• 125 NUCLEUS stations funded by NSF through UNAVCO that have been integrated into the Plate Boundary Observatory in 2008.
• 95 stations along the San Andreas Fault and in the urban area of Los Angeles that are operated by the US Geological Survey Pasadena field office.
• The remaining stations that are operated and maintained by the Scripps Orbit and Permanent Array Center , Jet Propulsion Laboratory and other agencies.
