Data holdings from the GPS Seamless Archive Center (GSAC) are available through an online interactive query-building process. This tool allows the user to locate GPS data files primarily through discovery, summary and quality-checking of GPS monument metadata. Processed GPS products are produced by Analysis Centers at Central Washington University and the University of California, Berkeley and the Analysis Center Coordinator at the Massachusetts Institute of Technology. The products include GPS solutions in standard SINEX format, as well as station position time series and network velocity fields.
GPS data products, and the raw data from which they are derived, are stored at the UNAVCO Facility GPS archive. The raw data and higher level data products are documented and available from the PBO GPS Products web page. RINEX data for individual stations may also be obtained directly from the UNAVCO Facility Permanent Station Archive.
More Info
The PBO GPS network will consist of 852 continuously operating stations, more than 400 of which are operating as of August 2006. All raw data collected by these stations are available at the UNAVCO Facility archive, in both Trimble T00 format and RINEX format. In addition, metadata related to these stations are available in standard IGS site log format.
PBO has two GPS Analysis Centers at Central Washington University and the New Mexico Institute of Mining and Technology, and one GPS Analysis Center Coordinator at MIT, that process raw GPS data from the PBO network, Nucleus network, and selected other stations. This team produces a range of GPS data products, including position solutions in SINEX format, GPS station position time series, and a network velocity solution.
