Application of Parallel Computing for Space Debris Close Approach Analysis

摘要：

Collision threat is becoming a serious problem since the amount of space debris increases fast recently.Besides, the detective capabilities are enhanced year by year.Thus calculation time cost on orbital data processing and close approach analysis gets much longer.Single processor cannot meet the requirements to keep the analysis results up to date.We review the procedure of close approach analysis and its time cost on single processor computer, and introduce several methods weve adopted to boost up the entire procedure.Finally we show a system of parallel computing environment on a high performance computer realized in National Astronomical Observatory for the purpose of collision risk assessment.
