PBO Nucleus | UNAVCO Facility

The PBO Nucleus project was developed as a means of incorporating the long time series of existing GPS networks into the measurement record of the Plate Boundary Observatory (PBO), thus optimizing the scientific potential of the NSF funded EarthScope project. PBO, designed as the geodetic component of EarthScope, studies the three-dimensional strain field in the western United States resulting from tectonic deformation across the Pacific-North American plate boundary.

The six existing western United States networks included in the Nucleus project are the Alaska Deformation Array (AKDA), the Bay Area Regional Deformation Network (BARD), the Basin and Range Geodetic Network (BARGEN), the Eastern Basin and Range and Yellowstone GPS Network (EBRY), the Pacific Northwest Geodetic Array (PANGA), and the Southern California Integrated GPS Network (SCIGN). Approximately half of these 432 stations were chosen to be upgraded by September, 2008, at which time they will be subsumed by PBO.

The process of upgrading the existing GPS stations from independent, region-specific operations to a streamlined "PBO-style" network is well underway. As of 12-February 2008, 197 of the 210 Nucleus stations have been upgraded with Trimble NetRS receivers, IP-based communications, and improved power systems as necessary. Two more sites are upgraded with NetRS receivers and remain on manual download pending installation of IP-based telemetry. Links to raw and RINEX data from the Nucleus GPS network can be found in the left column of this page.
