SOPAC Projects

NASA REASoN The NASA REASoN (Research, Education and Applications Solutions Network) cooperative agreement project "GPS Data Products for Solid Earth Science" provides GPS data products for sites in western North America, including the Southern California Integrated GPS Network (SCIGN). A legacy SOPAC SCIGN resources page is also available.

California Spatial Reference Center (CSRC) provides necessary geodetic services to ensure accurate and consistent spatial referencing of information within California.

California Real Time Network (CRTN) provides real-time GPS connectivity in California.

Plate Boundary Observatory (PBO) is a facility for investigating active tectonic and magmatic processes of the Pacific/Juan de Fuca - North American plate boundary through measurements of crustal deformation. SOPAC archives and analyzes PBO data in support of the NASA REASoN project.

Sumatran GPS Array (SuGAr): SOPAC archives RINEX data for this network of GPS stations along the Sumatran plate boundary

GPS Seamless Archive Center (GSAC) is a collection of GPS data archives and their operating agencies who agree to exchange information about their individual data holdings in order that users need not contact each archive separately to locate desired information.

Parkfield GPS Sites Information is available here regarding several GPS sites installed in the Parkfield, CA area as part of the SCIGN/BARD arrays, and their real-time data status.

Central California Irrigation District GPS Site Installation Project Two GPS sites are to be installed in the Central Valley, CA area as part of the BARD array.

GPS Meteorology SOPAC supports GPS meteorology research at the Global Systems Division GSD in the Earth Systems Research Laboratory ESRL at NOAA. Find out more here, along with a map of GPS sites with meteorological packages.
