An end-to-end battlespace space weather mission planning, simulation, and operations capability with effects on microelectronics will be developed. The new capability will provide accurate characterization of missile trajectory scenarios through the space weather environment. The capability will use the latest advances in space weather operations to specify and forecast the magnetic cutoff rigidities affecting both galactic cosmic rays (GCRs) and solar energetic particles (SEPs) as well as to monitor the actual GCR and SEP rates for improving the estimation of microcircuit susceptibility to single event effects (SEEs). Phase I demonstrated proof of concept by: extrapolating predictions from the latest space weather models to missile defense altitudes, developing an external Application Programming Interface (API) that ties the mission specific trajectories with environments, and generates output data. Phase II will concentrate on refining space weather environment models to provide greater accuracy and real-time capabilities, demonstrate exposure-effects calcuations on microelectronics, enhance the external API developed during Phase I, and, in parallel to the API, begin work towards integrating the tool into Systems Tool Kit/Space Environment and Effects Tool (STK/SEET). The Phase III objective is to develop the complete battlespace mission package and attain operational capability. Approved for Public Release 15-MDA-8169 (20 March 15)
