摘要
卫星的磁洁净度是影响空间磁场测量精度的关键因素之一。为了在设计阶段预估“张衡一号”卫星的磁洁净度,文章提出一种基于单机多磁偶极子模型的卫星磁性建模与仿真计算方法:首先通过单机磁场测量数据构建单机多磁偶极子模型;然后根据单机的安装位置和方向组合成整星磁性模型;进而仿真计算卫星绝对磁场校准装置位置处的磁场。整星磁试验验证结果表明,该仿真方法可信有效,可应用于同类高磁洁净卫星的磁性建模与仿真计算。
The magnetic cleanliness of satellites is one of the key factors affecting the precision of space magnetic field measurement.In order to estimate the magnetic cleanliness of Zhangheng-1 satellite in the design stage,a magnetic modeling and simulation method based on a single-machine multiple magnetic dipole model was proposed.First,a single-machine multiple magnetic diple model was constructed using its magnetic field measurement data.Then the whole satellite magnetic model was formed with a combination of the installation positions and directions of single-machines.In the end the magnetic field at the absolute magnetic field calibration device of the satellite was calculated.The results of the whole satellite magnetic experiment show that the simulation method is reliable and effective.This method may be applied to the magnetic modeling and simulation of similar high magnetic cleanliness satellites.
