低轨道卫星（飞行高度在300至800公里之间）进行的高精度磁测量允许研究电离层和磁层过程以及电流，这些过程在地磁安静条件下仅产生几纳特斯拉的微弱磁特征。对这一努力特别重要的是空间中的多点观测，例如由暖卫星星座任务提供的观测，以便更好地描述当前系统的时空结构。在地磁安静条件下，我们提供了电离层和磁层源的概述，并通过swarm卫星观测说明了它们的磁特征。
High-precision magnetic measurements taken by LEO satellites (flying at altitudes between 300 and 800 km) allow for studying the ionospheric and magnetospheric processes and electric currents that causes only weak magnetic signature of a few nanotesla during geomagnetic quiet conditions. Of particular importance for this endeavour are multipoint observations in space, such as provided by theSwarmsatellite constellation mission, in order to better characterize the space-time-structure of the current systems.Focusing on geomagnetic quiet conditions, we provide an overview of ionospheric and magnetospheric sources and illustrate their magnetic signatures withSwarmsatellite observations.
