Abstract:
This paper/talk describes the Space Domain Awareness (SDA) Environmental Toolkit for Defense (SET4D) migration and modernization of DoD space environment data and modeling capabilities to a GovCloud architecture and attribution tools for satellite anomalies, electro-magnetic interference (EMI), and launch and predict impact (L&PI) assessments. During the cloud migration, SMC/SPG is modernizing the technology and capabilities to focus on space environment impacts to SDA, USSF, and DoD warfighters. Taking advantage of streamlined research-to-operations (R2O) and cloud architecture features, the SMC, contractor, and federally funded research and development center team have developed and are operationalizing flowcharts for a preliminary determination of whether an operational satellite anomaly, an EMI impact, or a reported L&PI may have been caused by the space environment. The satellite anomaly flowcharts address single-event effects, event total dose on thinly shielded components, internal charging, and surface charging. The EMI flowcharts address shortwave fades, polar cap absorption, solar radio burst interference, scintillation, auroral clutter/interference, and rain attenuation. The L&PI flowcharts address the same satellite and EMI hazards with the addition of reflected solar illumination or glint, radar ducting/anomalous propagation, meteor shower and sun-in-sensor hazards.
