      abstract     = {Single event effects generated by ionizing radiation cause
                      a variety of problems inside satellitesup to mission
                      failures. In case of COTS-based nanosatellites, much effort
                      has to be investedin mitigation measures and redundancy
                      concepts. Increasingly, longer mission durations aretargeted
                      for imaging instruments used as remote sensing devices,
                      e.g., to observe long-termclimate processes. Highly
                      integrated System-on-Module (SoM) architectures enable high
                      processing performance for imaging applications with low
                      resource requirements in terms of powerand mass. The major
                      advantages of these architectures are flexibility,
                      (re)programmability,modularity and module reuse. In order to
                      achieve a fault tolerant design we modeled the radiation
                      environment, estimating the hazards at module level with the
                      objective to reduce therisks to an acceptable level by
                      applying appropriate mitigation techniques. This approach
                      results in an electronics design that combines hardware and
                      software redundancies paired withreconfiguration strategies
                      to assure system availability and reliability for mission
                      lifetime longerthan 3 years in Low-Earth-Orbits (LEO). In
                      this contribution, we will present a dual-imagerelectronics
                      that uses an SRAM-based Xilinx Zynq-7000 architecture, which
                      can accommodatea wide variety of imaging sensors in visible
                      and near infrared spectral range and is part of alimb
