Applications of real-time GPS for science and hazard monitoring



Real-Time GPS Position Data Products and Formats Boulder, Colorado, 26–28 March 2012 Recent advances in GPS technology and data processing are providing position solutions with centimeter-level precision at a high rate (1 hertz) and low latency (i.e., the time required for data to arrive for analysis, in this case less than 1 second). These data will have the potential to improve scientists' understanding in diverse areas of geophysics including properties of seismic, volcanic, magmatic, and tsunami sources, and profoundly transform rapid event characterization and warning. Scientific and operational applications also include glacier and ice sheet motions, tropospheric modeling, and space weather. Processed Real-Time GPS (RT-GPS) data will require formats and standards that allow this broad community to utilize these data and associated metadata in existing research infrastructure.
