摘　　要：分析了地球静止轨道(GEO)环内的物体现状,引入美国家航空航天局(NASA)的标准解体模型,给出了卫星撞击解体算法,编写了数值仿真软件,仿真研究了GEO卫星撞击解体形成碎片的特征及其轨道分布。结果表明:撞击会产生大量碎片,对空间环境造成长期的严重危害。研究结果对分析卫星撞击解体特性、保护空间环境有一定的参考价值。The situation in geosynchronous earth orbit （GEO） ring was analyzed in this paper. The NASA＇s standard breakup model was introduced, and the breakup algorithm was presented and the numerical simulation software was programmed. The characters and orbit distributions of debris induced by satellite collision breakup in GEO were studied by simulation. The results showed that the collision would produce a great deal of debris, and threat badly the space environment in many years. The research had some reference to analyze characteristics of satellite collision breakup and protect space environment.
