AB: The UNAVCO Facility is charged with implementing the campaign GPS component of the Plate Boundary Observatory (PBO) to support EarthScope investigators through a pool of approximately one hundred mobile GPS systems. In contrast to the PBO continuous GPS network, the PBO campaign systems are designed for temporary deployments with periods ranging from several minutes to several months per site. This allows researchers to conduct spatially and temporally focused investigations into a wide range of phenomena, including volcano monitoring, post-seismic deformation monitoring, and ground control for airborne LIDAR surveys. A standard PBO campaign system consists of a Topcon GB-1000 dual-frequency GPS receiver, a Topcon PG-A1 compact GPS antenna, an 18 Ah battery, cabling, a portable and waterproof Pelican case enclosure, and a Tech 2000 GPS antenna mast or tripod and tribrach. Available ancillary equipment includes solar panels, additional batteries, enclosures and mounting hardware. Communications equipment such as radio modems and cellular modems are also available to allow remote data retrieval during longer term deployments. We present an overview of the PBO campaign equipment available to investigators, technical specifications of the system, examples of current and planned EarthScope research projects utilizing the campaign equipment, and a hands-on demonstration of a PBO campaign system.
