The energetic electrostatic analyzer has been developed to act as a miniaturized, rugged, and low-cost instrument capable of providing in situ measurements of ion or electron energy and subsequent derived density, temperature, and spacecraft potential. We present laboratory calibration results using a magnetically filtered low-Earth-orbit plasma simulator to quantify the effects of spacecraft charge on laminated analyzer ion energy distribution measurements and the resulting impact on the derived temperature and density values. The calibration results are then applied as an empirical correction method to Space Test Program Satellite-3 integrated miniaturized electrostatic analyzer data to present corrected temperature and density values. Application of the empirical correction factor improved the agreement between in situ measurements and the international reference ionosphere model in terms of ion temperature by 0.01 eV and in terms of density to within 20%.

高能静电分析仪已被开发为小型化、坚固耐用且成本低廉的仪器，能够提供离子或电子能量以及随后导出的密度、温度和航天器电位的原位测量。我们使用磁性过滤的低地球轨道等离子体模拟器呈现实验室校准结果，以量化航天器电荷对层压分析仪离子能量分布测量的影响以及由此产生的对衍生温度和密度值的影响。然后将校准结果作为经验校正方法应用于空间测试计划卫星 3 集成微型静电分析仪数据，以显示校正后的温度和密度值。
