RADIATION-INDUCED ANOMALIES IN SATELLITES

Radiation-induced anomalies are discussed and a compilation of known e vents in semiconductor devices and electronic systems in commercial an d government satellites is provided. The various types of anomalies th at have been observed and the interactions of space radiation with dev ices are described. The number of events is limited to those occurring in some government (NASA, National Oceanic and Atmospheric Administra tion) and commercial spacecraft. In general, manufacturers are relucta nt to disclose their failures, and so these sources of events are not readily available. In the case of government spacecraft, anomalies on Department of Defense classified and unclassified satellites are not o ften reported. Thus, the list of events here is not complete, It repre sents only the proverbial tip of the iceberg. An important message for satellite designers is to anticipate this environmental threat and pr ovide remedies or safeguards.
