Research Institution
In Phase II, Propagation Research Associates, Inc., (PRA) proposes to complete the development of a real-time nowcast of ionospheric scintillation impacts on GPS users. Continuing its partnership with NASA’s Jet Propulsion Laboratory, PRA will implement real-time production of a map of ionospheric scintillation parameters over the United States using real-time data streamed from the National Geodetic Survey’s CORS network. PRA will mature the user experience model of scintillation impacts developed in Phase I and produce it in real time. PRA will then implement a web-based specification product to communicate the scintillation impacts in a format that is both easily understood and allows the user to access as much or as little detail about the impacts as he or she desires. PRA will also study the feasibility of 1) using an expanded set of real-time GPS data to enlarge the nowcast to areas outside the United States and 2) forecasting scintillation effects using existing NOAA SWPC nowcast and forecast products.
