Description
In the last few years, interest in constellations of satellites has significantly increased, especially in the context of the so-called New Space economy. Indeed, many commercial ventures or entrepreneurs now consider constellations as an efficient and affordable way to provide large access to pictures of Earth, world-wide access to the Internet, and many other services relying on data broadcast, collection or fusion. This new evolution in space industry mainly results from two game-changers: a more affordable access to space, proposed by companies such as SpaceX for instance, and most importantly availability of powerful, and yet cheap, COTS components, designed to be robust enough to radiations through mitigation techniques.
However, manufacturing, validating, launching and then operating satellites in large quantity is still a challenging endeavour. This paper will focus on the avionics subsystem that has been directly impacted by emergence of powerful COTS components. In particular, it will discuss several topics such as use of COTS from mainstream to space industry or Fault Detection, Identification and Recovery and Operations strategies.
