低轨星座系统电磁发射可视化技术研究

针对国内外低轨卫星互联网的高速发展,O3b、OneWeb、starlink、Teleost、LEOsat等低轨互联网系统的逐步完善并覆盖全球,此时不同星座系统卫星覆盖波束相互叠加,带来了频谱态势的复杂化,给其他系统带来了干扰隐患。与此同时,随着各个星座系统的部署运营,地球所处电磁环境将变得复杂多变、电磁干扰情况发生的频次和程度更为严重。为准确量化评估低轨卫星系统的电磁干扰,本文通过研究低轨星座卫星系统的电磁发射模型,结合轨道运动学研究电磁发射覆盖范围的动态分析法,实现低轨星座卫星电磁发射的可视化。

Research on electromagnetic emission visualization technology of low orbit constellation system

For the rapid development of low orbit satellite Internet at home and abroad,O3b,OneWeb,starlink,Teleost,LEOsat and other low orbit Internet systems gradually improve and cover the whole world.At this time,the satellite coverage beam of different constellation systems overlaps with each other,which brings about the complexity of spectrum situation and brings the potential interference to other systems.At the same time,with the deployment and operation of each constellation system,the electromagnetic environment of the earth will become complex and changeable,and the frequency and degree of electromagnetic interference will become more serious.In order to accurately and quantitatively evaluate the electromagnetic interference of low orbit satellite system,this paper studies the electromagnetic launch model of low orbit constellation satellite system and combines the dynamic analysis method of orbit kinematics to study the coverage range of electromagnetic launch to realize the visualization of low orbit constellation satellite electromagnetic launch.
