高级研究和全球观测卫星（ARGOS）自1999年2月以来一直在运行，包括三个光谱仪，组成高分辨率气辉和极光光谱学（HIRAAS）实验。HIRAAS仪器遥感地球的中、远和极紫外气辉，以研究热层和电离层的密度、组成和温度。低分辨率气辉和极光光谱仪（LORAAS）是一种覆盖80-170 nm通带的边缘扫描仪，光谱分辨率为1.8 nm。对热O型和B型恒星的反复偶然观测被用来改进方位解，表征仪器视场，并监测使命期间仪器的相对灵敏度退化。我们提出了性能表征的方法，并报告所观察到的LORAAS楔条微通道板检测器的性能下降。本文的方法和结果可以直接用于在DMSP Block 5D3卫星上飞行的SSULI操作传感器的在轨表征。
The Advanced Research and Global Observation Satellite (ARGOS) has been operating since February 1999 and includes three spectrographs comprising the High Resolution Airglow and Auroral Spectroscopy (HIRAAS) experiment. The HIRAAS instruments remotely sense the Earth's mid-, far- and extreme-ultraviolet airglow to study the density, composition, and temperature of the thermosphere and ionosphere. The Low Resolution Airglow and Aurora Spectrograph (LORAAS) is a limb scanner covering the 80-170 passband nm with 1.8 nm spectral resolution. Repeated serendipitous observations of hot O- and B-type stars have been used to improve the aspect solution, characterize the instrument field-of-view, and monitor relative sensitivity degradation of the instrument during the mission. We present the methodology of performance characterization and report the observed performance degradation of the LORAAS wedge-and-strip microchannel plate detector. The methods and results herein can be utilized directly in on-orbit characterization of the SSULI operational sensors to fly aboard the DMSP Block 5D3 satellites.
