Potential NASA Commercial Applications: Pay-off from this SBIR investment is enormous because it utilizes already-developed and validated space weather algorithms to solve the urgent problem of ionospheric nowcasting and forecasting. The IDA4D/AMIE products will be delivered to the NASA CCMC, our first customer, in Phase-II. NASA has declared their interest in running these codes in real-time as part of a near real-time data-assimilative model, for both solar quiet and active times, which allows for precise specification and forecasts of the space environment, beginning with solar eruptions and propagation, and including ionospheric electron density specification. We expect that NASA will ask ASTRA for help transitioning the software from TRL-5 at the end of Phase-II, to TRL-9 during a Phase-III effort. The resulting data assimilative algorithms will be transformative for space weather operations at NASA, especially for ionospheric nowcasting and forecasting. High-fidelity specifications of the ionospheric electron density, like those from IDA4D, are required by NASA for many applications, including scientific analysis, communications system operations, and mission planning. Knowledge of the electron density is relevant for projects like electrodynamic tethers, and satellite radar interferometry. This will have immediate applications in mission planning, radio frequency (RF) communications, surveillance, and navigation systems, and the US electrical power grid. Total NASA revenues over 10 yrs estimated at $3.6M.
