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.},
