Abstract为解决空间引力波探测任务中航天器磁场对惯性传感器干扰的问题,研究在航天器复杂磁环境下利用主动测控方式获取小尺度均匀磁场环境的方法.在惯性传感器周围进行分布式磁场探测,并采用球谐函数法或多磁偶极子法实现对惯性传感器外部磁源的估计,计算惯性传感器所处位置的空间磁场及其梯度分布.利用线圈技术,对磁场及其梯度进行线性补偿.讨论分析传感器数量以及磁源布局方式等因素对最终补偿效果的影响.仿真试验结果表明,通过这一方法可将惯性传感器所在区域的磁场及其梯度降低1~2个数量级,降低引力波航天器平台的剩磁控制压力,为引力波探测提供满足要求的磁场环境.
Other AbstractIn order to solve the problem that spacecraft magnetic field interferes with inertial sensor in the mission of gravitational wave detection.A method of acquiring small-scale uniform magnetic field environment by measurement and active compensation in spacecraft complex magnetic environment is introduced.Magnetic source around inertial sensor and the magnetic field as well as its gradient distribution near inertial sensor can be obtained by distributed magnetic field detecting combined with spherical harmonic function and multi-magnetic dipole method.By properly setting coils,the linear compensation of magnetic field and the first order tensor can be realized.The influences of sensor number,magnetic source layout and other factors on the final compensation effect are discussed.Simulation results show that this method can reduce the magnetic field and its gradient near inertial sensor by 1 ~2 orders of magnitude,which can reduce residual magnetic control pressure of gravitational wave spacecraft platform and provide a magnetic field environment satisfying the requirements of gravitational wave detection.
