某型号卫星磁性分析与控制

某型号卫星的有效载荷之一高能望远镜对磁场敏感，因此在设计阶段即需分析卫星在轨时载荷所处的磁场环境，并尽可能提高载荷的抗磁场干扰能力。文章根据卫星的构型，对整星的磁场分布进行了计算；对载荷的抗磁场干扰能力进行了测试；对载荷的磁屏蔽方案进行了仿真与测试；分析了抗磁场干扰设计对整星磁性控制的影响，证明卫星可以满足总磁矩不大于5.0 A?m2的姿态控制要求。

Magnetism analysis and control for a satellite

High energy telescope is an important payload of a certain satellite and it is sensitive to magnetic field. Therefore, its design requires an analysis of the magnetic environment while the satellite is on the orbit in order to better counteract the magnetic disturbance. In this paper, the magnetic distribution about the satellite in accordance with its structure is calculated, the payload’s ability to counteract magnetic disturbance is analyzed, and the schemes of load’s magnetic shielding are compared.
