摘要

Space debris represents a significant risk to satellite operations, due to the possibility of damaging or catastrophicrncollisions. Consequently, many satellite operators screen the orbiting population for close approaches with their onorbitrnassets and a public conjunction assessment service, Satellite Orbital Conjunction Reports AssessingrnThreatening Encounters in Space (SOCRATES), generates close approach predictions on a daily basis for all satelliternpayloads in the catalogue. These screening capabilities are used to inform operational decisions relating to riskrnmitigation but it is anticipated that the demands placed on these services will increase as debris becomes morernprolific. This hypothesis is explored in a preliminary analysis of conjunction data for the years 2004 to 2009 and arnnew ‘Business As Usual’ study using the Debris Analysis and Monitoring Architecture for the GeosynchronousrnEnvironment (DAMAGE) model. The results suggest a 50% increase in the number of close approaches reported byrnSOCRATES (or its equivalent) within the next ten years. By 2059, daily conjunction reports could contain overrn50,000 close approaches below 5 km, affecting the demands placed on tracking facilities and satellite resources.
