地球轨道空间碰撞风险区域态势分析

COLLISION RISK ANALYSIS OF ORBITAL AREAS IN EARTH SPACE

  • 摘要: 太空中的人造目标数量持续加速增长,地球轨道空间已变得愈发拥挤,在轨卫星运行中面临的碰撞风险日益升高。本文基于公开的大量空间目标编目轨道数据,对当前空间环境下在轨卫星面临的碰撞威胁程度进行了简要计算和分析,给出不同轨道区域中卫星的碰撞风险等级,并指出了几个碰撞风险显著偏高的典型区域。最后,从空间碎片环境安全角度出发,对卫星轨道选取提出建议,可为待发射卫星的轨道部署提供参考。

     

    Abstract: As the number of man-made objects in space continues growing, the Earth's orbital space has become more crowded, and there is a growing risk of collision for on-orbit satellites. Based on the public orbital data of a large number of space objects, this paper calculates and analyzes the degree of collision risk for on-orbit satellites in the current space environment, gives the collision risk level in different orbital regions, and points out several typical areas with significantly high collision risk. Finally, from the perspective of the safety of the space debris environment, several pieces of advice are suggested for the deployment of satellite orbits, which can be referred for the satellites to be launched.
