SLAC GPS Station M40
SLAC's existing GPS base-station has been upgraded and in addition to providing RTK site surveys it now also contributes to the solid earth research community (See Interaction Point article). The base-station was added to the Plate Boundary Observatory (PBO) on September 26th. This is part of the EarthScope project funded by the National Science Foundation studying the three-dimensional strain field resulting from deformation across active plate boundaries in the Western United States. A Memorandum of Understanding (MOU) between SLAC and the University NAVSTAR Consortium (UNAVCO) regarding participation in the PBO was signed in early September 2005. See SLAC UNAVCO MOU.
