Development of space environment customized risk estimation for satellites (SECURES)

Abstract Plasma variations in the geospace environment driven by solar wind–magnetosphere interactions are one of major causes satellite anomaly. To mitigate effect anomaly, risk space weather disturbances predicted forecasting needs to be known advance. However, anomaly owing is not same for all satellites, because depends only on itself but also design and materials individual satellites. From viewpoint operators, it difficult apply a general alert level provide tailored information, we have developed SECURES (Space Environment Customized Risk Estimation Satellites) combining models those spacecraft charging. In SECURES, focus charging (surface/internal) geosynchronous For estimation surface charging, combined global magnetosphere magnetohydrodynamics (MHD) model with models. internal radiation belt We prototype products both types charging/electrostatic discharge (ESD). The development our achievements introduced this paper.
