摘要
研究尾迹效应和地磁场效应对中低轨道航天器表面充电的影响。根据航天器表面充电机制，采用薄鞘模型；根据电流收集和轨道反演方法进行了数值模拟，给出航天器表面为导体和非导体的平衡电位，并进行了分析研究。数值结果观测和理论分析相符。
This paper presents the effects of geomagnatics and wakes on spacecraft surface charging in low orbit.According to the charging mechanism,a numerical simulation is set up by using current collection and “inside out”method of particle tracing,the surface equilibrium potentials of the conductor and non conductor surface of spacecraft are given.The numerical calculation,results agree with the observation and the theoretical analysis.
