Global Positioning System Data at SCEC

The SCEC_DC archive of GPS data aims to contain data from "survey-mode" precise GPS measurements made in Southern California by various universities, Federal organizations (notably the US Geological Survey and the National Geodetic Survey), the California Department of Transportation, and several southern California Counties.

Data from continuous GPS stations are archived for SCEC at the Scripps data center; for the Los Angeles basin network some information is also available from the USGS and from JPL.

CURRENT DATA ARCHIVE

The main data archive is of RINEX format files; there is a parallel archive of raw data files which is not generally accessible.

A set of maps of GPS stations has been produced to help with planning of future observations, by showing where past ones have been made.

Some additional information about the data in this archive are available from the UCLA GPS group.

PLANS FOR A LARGE GPS ARRAY

A SCEC Workshop "Geological and Design Issues of Continuous GPS Networks" has been held to discuss the design and planning for a large-scale continuous GPS network.
