太阳轨道飞行器任务中的磁强计仪器旨在整个任务期间持续测量航天器附近的磁场。不仅需要描述背景磁场的特征，还需要描述其在从远高于到远低于质子回旋尺度的范围内的变化，这对稳定性、精度和噪声提出了具有挑战性的要求，同时对航天器和其他仪器也有磁性和操作方面的限制。具有挑战性的振动和热环境促使机械传感器设计有了重大发展。本文描述了仪器的整体设计、性能、数据产品和操作策略。
The magnetometer instrument on the Solar Orbiter mission is designed to measure the magnetic field local to the spacecraft continuously for the entire mission duration. The need to characterise not only the background magnetic field but also its variations on scales from far above to well below the proton gyroscale result in challenging requirements on stability, precision, and noise, as well as magnetic and operational limitations on both the spacecraft and other instruments. The challenging vibration and thermal environment has led to significant development of the mechanical sensor design. The overall instrument design, performance, data products, and operational strategy are described.
