Background and Focus:

The aerospace market has undergone rapid changes within the last 15 years. Due to technological progress in consumer electronics
satellite design has evolved from the purely use of customized hardware solutions towards the utilization of commercial off-the-shelf
electronics, potentially leading to higher cost efficiency and an increased system performance. The dawn of the CubeSats and
upcoming Mega-Constellations of miniaturized satellites are currently fueling the progress, attracting venture capital in a never seen
before ratio. Mega-Constellations of satellites for a diverse range of applications have become reality with the successful funding of
OneWeb, with a total investment of $500 Million. 2015 has been the year with the single most venture capital investments in spaceflight.
While using COTS electronics, such missions require an increased level of dependability in all subsystems to enable their use within
critical missions and for such with prolonged lifetime requirements. However, miniaturized satellites are plagued by low
dependability, and require failure tolerance and reliability-enhancing measures to be implemented. Furthermore, on board computers
of such spacecraft need to take into account specific boundary conditions which can differ significantly from those of standard
computing systems. These comprise environmental factors like launch loads or radiations robustness but also limitations regarding
power consumption, mass or costs.
The workshop will discuss existing and novel approaches for computer architectures in space, targeting an audience from computer
architects to space engineers working on miniaturized as well as traditional larger scale satellites. Synergies to existing terrestrial
applications as well as computing architectures of constellations and swarms of satellites are a focus of the workshop, being firmly
embedded in the main conference. The ARCS conferences series has over 30 years of tradition reporting leading edge research in
computer architecture and operating systems.
