| Abstract: | Data Device Corporation’s SCS750 single-board computers (SBCs) have been operating without interruption onboard the Gaia satellite since its launch in 2014. The uninterrupted operation is possible because of several hardening techniques that allow the SBC to correct single-event upsets (SEUs) in the constituent components. We present on-orbit SEU data for the SBCs. All errors analyzed here were corrected by the SBC and had no effect on mission operation. We analyze the data to determine the accuracy of current models, as well as the effects of the space weather environment. [ABSTRACT FROM AUTHOR] |
