Orbital Debris Conjunction Screening at Constellation Scale: A Technical Note on Alert Thresholds

Abstract

There is real interest in orbital debris conjunction screening at constellation scale right now, and real uncertainty about exactly
where it delivers the most value. We pull together the current evidence for orbital debris conjunction screening at constellation
scale, covering the methodological, practical, regulatory and cost angles, with an eye on where practice has genuinely settled and
where researchers and reviewers are still largely working it out for themselves. Selective, context-specific pursuit looks better
supported by the evidence gathered here than either broad rollout or blanket avoidance.
