摘要

FY-3E卫星等离子体分析仪标志着中国首次探测到了黎明-黄昏轨道空间典型等离子体环境的特征、发生和发展。它为业务化空间天气警报和预报提供数据源支持，有助于确保卫星在轨安全，并为空间环境建模和空间物理研究积累空间环境探测数据。本文详细介绍了 FY-3E 卫星等离子体分析仪所采用的探测技术。我们通过校准实验对其性能进行了校准，然后与国内同类仪器进行了分析和比较。结果表明，该仪器能够测量 24 eV~32 keV 的离子能谱和 23.7 eV~31.6 keV 的电子能谱，视场角达到 180°×90°，航天器绝对电位的反向测量范围优于-30 kV~+30 kV。所有这些都有助于显著提高中国低地轨道卫星等离子体和卫星电位探测技术。

FY-3E Satellite Plasma Analyzer

The FY-3E satellite plasma analyzer marks China’s first detection of the characteristics, occurrence, and development of the typical plasma environment in the dawn–dusk orbit space. It provides data source support for operational space weather alerts and forecasts, helps ensure the in-orbit safety of the satellite, and accumulates space environment detection data for space environment modeling and space physics research. This paper gives a detailed introduction to the detection technology adopted by the FY-3E satellite plasma analyzer. We calibrated its performance through a calibration experiment and then analyzed and compared it with similar instruments in China. It is indicated that the instrument is capable of measuring an ion energy spectrum of 24 eV~32 keV and an electron energy spectrum of 23.7 eV~31.6 keV, its field of view reaches 180° × 90°, and the inversed measurement range of spacecraft absolute potential is better than −30 kV~+30 kV. All these contribute to a notably improved technology for plasma and satellite potential detection of China’s LEO satellites.
