The Center for Real-Time GPS Data and Environmental Products (the Center) will transform NASA's unique Global Differential GPS (GDGPS) system from a proof-of-concept prototype into a robust, self-sustaining Service Center, with unparalleled capability to collect, synthesize and disseminate the diverse data from GPS and other Earth monitoring platforms that are increasingly available in real-time. We will offer a broad array of real-time products and services that will usher in a new capability to anticipate, assess, and respond to environmental changes that occur on short time scales, such as earthquakes, volcanic eruptions, hurricanes, and weather in general. The Center will enable the monitoring of the Earth observing platforms themselves, and the timely calibration, quality control, and dissemination of their science data. This effort represents a significant leap in the fundamental capabilities of the Earth Science Enterprise to observe, monitor, and interpret the Earth. The broad science, national, and civil benefits extend well beyond NASA. Of particular note is the unparalleled capability for real-time monitoring of the performance of the GPS constellation itself. This capability will result in profound national benefits because of the key role GPS plays in our national security and every-day life.

The emerging solid customer base for the GDGPS real-time products, which includes commercial companies, NASA missions, and non-NASA Government agencies, is a clear indication of the need for the development of a center for real-time GPS data and products, with excellent prospects for self-sustenance, and high return on investment value.
