Scripps Orbit and Permanent Array Center, Scripps Institution of Oceanography

Service Provider Description
The Scripps Orbit and Permanent Array Center (SOPAC) is located
at the Cecil H. and Ida M. Green Institute of Geophysics and
Planetary Physics (IGPP), Scripps Institution of Oceanography
(SIO), University of California, San Diego (UCSD) in La Jolla,
California. SOPAC's primary scientific role is to support high
precision geodetic and geophysical measurements using Global
Positioning System (GPS) satellites, particularly for the study
of earthquake hazards, tectonic plate motion, plate boundary
deformation, and meteorological processes. SOPAC investigators
also conduct research on the implementation, operation and
scientific applications of continuously monitoring GPS arrays
and Synthetic Aperture Radar (SAR) interferometry.

SOPAC is a major participant in the International GPS Service
(IGS), serving as a Global Data Center and a Global Analysis
Center. SOPAC is the archive for the 250-station Southern
California Integrated GPS Network (SCIGN), as well as an
analysis center and a data retrieval facility. SOPAC maintains
an archive of regional continuous GPS data for UNAVCO,
Inc. focusing on the Western North America plate boundary and is
developing a seamless archive interface for UNAVCO. SOPAC
performs research and provides operational support for NOAA's
Forecast Systems Laboratory (FSL) real-time GPS meteorology
project for short-term weather forecasting. SOPAC also provides
essential infrastructure support for the California Spatial
Reference Center (CSRC), a partnership with the National
Geodetic Survey (NGS).
