A Tool for Defining Solar Particle Access to the Magnetosphere (SPAM) for Satellite Anomaly Attribution

The goal of the proposed project is ultimately to provide a tool for commercial and government satellite operators and designers that can be used to identify the cause and monitor the real time likelihood of on-orbit satellite anomalies. More specifically, the tool will provide real time situational awareness and information for identifying whether an observed satellite anomaly is likely related to an impact from a Solar Energetic Particle (SEP). The work will fulfill the NASA need defined in the lsquo;Space Weather O2R/R2O Technology Developmentrsquo; subtopic. This subtopic solicits, lsquo;specifications and/or forecasts of the energetic particle and plasma conditions encountered by spacecraft within Earthrsquo;s magnetosphere, as well as products that directly benefit end-users such as spacecraft operatorsrsquo;. This project will fully address the subtopic request by providing both an energetic particle model and a tool that will translate that model output into both retrospective and real time actionable information for spacecraft operators and designers. During Phase I, the project will produce a data driven model of SEP access near Earth and evaluate its utility to the government and commercial satellite industry for understanding anomalies. In Phase II, the particle access model will be extended to include more species and energies and will be incorporated into a tool that allows users to input their satellite specifics and determine the precise particle flux and its impact at any location along any orbit at any time.
