The California Real Time Network (CRTN) is a UC San Diego research program started in 2001, with a significant education and outreach component linked to the California Spatial Reference Center (
CSRC). The primary purpose of CRTN is research on early warning systems for natural hazards using precise real-time GPS technology. It is led by Scripps Orbit and Permanent Array Center (
SOPAC) Director and Principal Investigator Yehuda Bock at the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics (
IGPP) at Scripps Institution of Oceanography (
SIO). SOPAC and its partners upgrade science-based continuous GPS stations in California to real time (less than 1 s latency) high rate (1 Hz) operations, and retrieve, disseminate, analyze and archive the data and data products. Maintenance of the real-time system is performed by SOPAC, with the assistance of Southern California Metropolitan Water District, San Diego's
Department of Public Works and
Sheriff's Department,
County of Orange Resources & Development Management Department, UCSD's
HPWREN project, and
Geodetics, Inc.
CRTN real-time data streams are available for a variety of real-time applications, as well as archived 1 Hz raw data files.
