Abstract:
Satellite collision avoidance analysis has received increased emphasis since the Iridium-COSMOS collision of February 2009, including serious consideration of regular all vs. all collision avoidance analysis of the entire space catalog by the US Air Force. This paper describes a technique for the very fast screening of large conjunction analysis problems. This technique makes no assumptions about orbit shape or motion and is suitable for the analysis of powered or hyperbolic flight with no special consideration required. Implementations of this technique (CSieve) on both cluster computers and large multi-core computers are presented including discussion of analysis scaling. Results are presented for all vs. all analysis of up to 93K objects. Discussion of batch vs. continuous analysis is also presented.
