摘　　要：空间科学发展对空间交流磁场(约20 kHz)的探测需求愈加凸显。减小探测器自身交流磁场对星载磁场传感器的干扰对于获得高精度空间磁场数据至关重要。2023年发射的JUICE木星探测器实现了世界领先的交流磁场控制。文中介绍了JUICE的磁场传感器配置和磁控指标,并归纳了交流磁场的来源;重点分析了JUICE的交流磁场指标估算,交流磁场测量,以及太阳电池板和反作用轮的磁场控制等关键技术;讨论了交流磁场控制与直流磁场控制的主要区别;总结了JUICE单机和整器的磁试验设备配置情况。有关实践可为我国后续空间磁场探测器的交流磁场控制技术研究和任务实施提供参考和指导。As space science advances,the demand for detecting AC magnetic fields(ACMF)in space continues to be highlighted.Reducing the interference of the ACMF generated by the spacecraft on onboard magnetic sensors is crucial for obtaining high-precision space magnetic field data.The JUICE probe,launched in 2023,has achieved a world-leading level of precision in ACMF control.This paper initially introduces the magnetic sensor configuration and control indicators of JUICE,followed by an overview of the sources of ACMF.Key technologies,including JUICE’s ACMF index estimation,ACMF measurement,as well as the optimization of solar panel and reaction wheel design for ACMF control,were examined.The main differences between ACMF control and DC magnetic field control were also discussed.Finally,the magnetic test equipment configuration for JUICE single units and the entire spacecraft was summarized.These practices provide references and guidance for the research and implementation of ACMF control technology in China’s future space magnetic field exploration missions.
