ACCEDE Workshop on COTS Components for Space Applications

Introduction

Since the first successful ACCEDE event in 2019, the usage of Commercial of the Shelf (COTS) EEE parts in space applications continue increasing. Furthermore, both: companies and institutions are hardly working to get knowledge and find methodologies to safely use them, not only for addressing needs of the so called “New Space” programs such as constellations and/or nano & small satellites, but also for reaching the technical challenges in the more classical space missions and applications.

Technical Scope

Nowadays, space sector is recognized as a highly competitive sector, asking continuously for higher performance figures while reducing the overall cost from missions inception up to end of life decommissioning. Such a trend has consequences at all levels down to the selection and procurement of building blocks and components.

In parallel EEE parts designed for ground application such as automotive, data handing, and other high demanding sectors start to show interesting performances and high reliability levels when produced in massive quantities and while being subjected to ad-hoc qualification schemes (por example AEC Q, but not only).

In the meantime several events have occurred: the ECSS-Q-ST-60-13 was deeply reviewed and it is in the process to be updated, recognizing in certain way the AEC Q system. Numerous initiatives have been also put in place: Space2motion at DLR, OSIP call at ESA, …. constellations model missions are growing: Starlink, OneWeb or Kuiper, and missions start to produce relevant data.

Although we could see the direct use of COTS as a solution, there is still a gap to be cover in order to allow a more systematic usage of COTS components for space applications.

With this in mind, the workshop intends to act as a forum for experts to share their experience and forecast based on facts and technical evidence.

Conference Logistics

Duration: Two and a half days.

Scheduled dates: Wednesday 5th to Friday 7th October 2022

City/ Venue: Seville (Spain)

Format: Mixed: virtual and on-site

Preliminary list of Topics

  • Mission classification and criteria to drive COTS usage acceptability.
  • Technological studies addressing reliability of EEE COTS for use in space:
    • Material issues: pure tin,…, etc.
    • New packaging: SIP,… aspects.
    • Lot traceability and variations understanding and management.
    • New technologies.
  • Parts selection processes
  • Radiation hardness assurance: new radiation validation processes, assessment of in-orbit anomaly and events data,…, etc.
    Radiation and reliability mitigation techniques: validity demonstration.
    COTS use cases: successes, problems and failures.
  • Diversity of COTS quality grades and normative systems: Industrial, Automotive, …, etc.
  • Data availability and accessibility on COTS (reliability, qualification,…) and its assessment.
  • EEE component manufacturers perspectives and options.
  • Component user perspectives.
  • Policy aspects and quality provisions in using COTS; standards validity, available guidelines, gaps…, etc.
  • Other associated factors to be addressed:
    • Impact on Reliability prediction
    • Derating policy validity and recommendations
    • Identification, handling and storage.

Presentations

The workshop is designed on invited oral presentations and talks gathered in sessions following a single track. The presentation duration will be in the range of 20 minutes including 5 minutes for questions.

Several “Panel discussion” are envisaged addressing the key-hot topics for the second day, with a key moderator and selected panelist speakers.

Those interested in particular topics and wishing to provide a presentation / talk are encouraged to contact the organizing committee as soon as possible at:
