%T In-flight Reconfiguration with System-on-Module based Architectures for Science Instruments on Nanosatellites
%M FZJ-2022-00800

%X 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.
