The Global Positioning System (GPS) is a constellation of 24 satellites which is used for navigation and precise geodetic position measurements. Daily position estimates are determined from satellite signals which are recorded by GPS receivers on the ground. Data from the IGS, SCIGN, BARD, CORS, BARGEN, and PANGA networks have been analyzed at the Jet Propulsion Laboratory, California Institute of Technology under contract with the National Aeronautics and Space Administration. Horizontal velocities, mostly due to motion of the Earth's tectonic plates and deformation in plate boundary zones, are represented on the maps by arrows extending from each site.
