6.0 GPS DATA

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 (notable the U.S. 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.

CONTENTS OF ARCHIVE

The GPS data archive consists of the following:


	1)    raw and RINEX format GPS data
	2)    site descriptions and log sheets
	3)    indexes to the data and the sites
	4)    solution files from the processed data

ARCHIVE DIRECTORY STRUCTURE

GPS data that has been RINEXED and checked for major quality problems is archived in the directories:

         /archive/gps/year/rinex/julian day
    e.g. /archive/gps/1994/rinex/199
