PROBA-II Technology Demonstration Module in-flight data analysis

A Technology Demonstration Module (TDM) to monitor radiation effects in semiconductor devices was part of the payload on-board the European Space Agency (ESA) PROBA-II satellite. PROBA-II was launched on November 2^nd 2009, into an 800 km polar orbit with the TDM switched-on since February 15^th 2010. The TDM primarily carries modern memory devices in order to monitor and record their Single Event Effect (SEE) behavior in respect to orbital positions. This paper presents details of in-flight data obtained between February 15^th 2010 and March 31^st 2011. Observed in-flight error rates are compared with predictions based on ground test data obtained on flight lot devices operating under identical conditions.
