货车艾伦探测器航天器飞越内辐射带和等离子体层，探测热大气层、电离层和极光下磁层之间极其动态的耦合。使用货车艾伦探针数据检查该区域的电动力学，需要在航天器运动产生的电场为~ 100 mV/m的区域中测量感兴趣的~ 1 mV/m电场（E场）。这意味着电场，磁场和航天器速度必须测量到优于1%。货车艾伦探测器上的仪器已经达到了这种精度，即使在三个地球半径以下也能提供可靠的近赤道电场测量。本评论的目的是总结多年来开发的方法，以最大限度地提高L = 3以下双探头电场测量的准确性和科学回报。
The Van Allen Probes spacecraft flew through the inner radiation belt and the plasmasphere, probing the extremely dynamic coupling between the thermosphere, the ionosphere and the subauroral magnetosphere. Examining the electrodynamics of this region using Van Allen Probes data required that the ∼1 mV/m electric field (E‐field) of interest be measured in a region where the E‐field due to spacecraft motion was ∼100 mV/m. This means that the E‐field, the magnetic field, and the spacecraft velocity had to be measured to better than 1%. The instruments on board the Van Allen Probes have achieved this accuracy, delivering reliable near equatorial E‐field measurements even below three Earth radii. The objective of this commentary is to summarize the methodology developed over the years to maximize the accuracy and scientific return of these double probe E‐field measurements below L = 3.
