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 to be integrated into the Plate Boundary Observatory in 2008.
95 stations along the San Andreas Fault and in the urban area of Los Angeles will be operated by the US Geological Survey Pasadena field office.
The remaining stations will be operated and maintained by the Scripps Orbit and Permanent Array Center , Jet Propulsion Laboratory and other agencies.

The NSF portion of the SCIGN array continues to be operated and maintained by the USGS Pasadena Field Office through an NSF sub-award to SCEC. The scign.org site will continue to be maintained during this three year transitional phase.
