    • PURPOSE: A system and a method for managing collision risk between satellites and space debris are provided to prevent satellites from being collided with space debris by correcting the orbits of the satellites in driving while estimating the orbits of the space debris. CONSTITUTION: A system for managing collision risk between satellites and space debris comprises an orbit estimating part(151), an probability calculating part(152), and a startup analyzing part(153). The orbit estimating part estimates the orbits of space debris based on the information on the orbits where the space debris moved and estimates the orbits of satellites based on the information on the orbits where the satellites moved. The probability calculating part calculates the collision probability between the space debris and the satellites based on the orbits of the space debris and the satellites estimated in the orbit estimating part. The startup analyzing part controls the orbits of the satellites based on the collision probability calculated in the probability calculating part.
    • 目的:提供用于管理卫星和空间碎片之间的碰撞风险的系统和方法,以通过在估计空间碎片的轨道的同时校正卫星的轨道来防止卫星与空间碎片相撞。 构成:用于管理卫星和空间碎片之间的碰撞风险的系统包括轨道估计部分(151),概率计算部分(152)和启动分析部分(153)。 轨道估计部分基于空间碎片移动的轨道上的信息估计空间碎片的轨道,并根据关于卫星移动轨道的信息估计卫星的轨道。 概率计算部分基于在轨道估计部分中估计的空间碎片和卫星的轨道来计算空间碎片与卫星之间的碰撞概率。 启动分析部根据在概率计算部中计算出的碰撞概率来控制卫星的轨道。
