      abstract     = {There is a great interest in cost-effective, reliable and
                      state-of-the-art computing performance for science payloads
                      on nanosatellite missions. Highly integrated system
                      architectures combine reconfigurable System-on-Chip (SoC)
                      devices, memory as well as peripheral interfaces in a single
                      System-on-Module (SoM) and offer low resource requirements
                      regarding power/mass, but moderate to high processing power
                      capabilities. The major advantages of these architectures
                      are flexibility, (re)programmability, modularity and module
                      reuse. However, it is a challenge to use radiation sensitive
                      SoM with COTS based memories devices in a low Earth orbit
                      (LEO).In order to fulfill the requirements, we developed a
                      remote sensing instrument for atmospheric temperature
                      measurements with mitigation measures, using redundant
                      memory devices and in-flight reconfiguration. The hardware
                      is based on the Xilinx Zynq-7000 SoM with minimal amount of
                      external components. A supervisor circuit is used to manage
                      save booting from alternative and redundant memory devices
                      and initiates event-triggered reconfiguration of the system.
                      The approach distinguishes between programmable logic and
                      processing system reconfiguration, and enables in-flight
                      firmware updates in the event of errors changing measurement
                      conditions.},
