Dependability of Electronic Systems in the International Space Station

This paper studies two issues related to the dependability of electronic systems aboard the International Space Station (ISS). It is first shown that it may be possible to increase fault-tolerant sensor reliability by using 3d printing to repair failed sensor housings instead of storing extra sensors in the ISS. Then, regarding error detection in FPGA-based circuits, a technique is developed which detects Single as well as Multiple Event Upsets with little extra area overhead. This technique is implemented on Xilinx as well as Cyclone devices to demonstrate its efficiency.
