Electrical anomalies on spacecraft due to hypervelocity impacts

摘要: One of the main challenges in satellite design is dealing with threat from space environment. Numerous spacecraft anomalies are reported on a regular basis and most these cases, it extremely difficult to diagnose cause anomalies/failures. Hypervelocity impacts meteoroids orbital debris has recently emerged as possible catalysts for electrical observed spacecraft. In this paper, we present case study statistical analysis hypervelocity impact-induced anomalies. We data showing anomalous currents power distribution system JASON-1 following impact. A carried out using 2413 Ascend anomaly database 5033 maintained 1990s by National Geophysical Data Center (NGDC). find that there no correlation between flux shower incidence For geostationary satellites, use NASA's Meteoroid Engineering Model calculate sporadic at different locations orbit rate significantly higher regions high average meteoroid flux. These results serve strong indicator damage caused electromagnetic emissions impacts.
