Celetrak’s SOCRATES conjunctions database is calculated twice-daily to aid spacecraft operations collision avoidance manoeuvres. This network shows conjunctions of less than 5 km between orbiting objects, including debris, on 29th October 2009.   Our team has expertise in applying network theory to space debris environment data to identify space debris objects for remediation. The team has the experience to enable them to apply generalised network theory to any system in which pairs of objects interact with one another.
