| 摘 要： | “张衡一号(简称ZH-1)”卫星搭载的三频信标机(tri-band beacon,TBB)载荷，能够对站链上空的电离层进行高精度测量.为检验TBB载荷在电离层监测中的应用效果，本文利用2018—2019我国中低纬地区TBB观测数据，采用求均值及多项式拟合的方法对各月份F2层峰值电子密度(NmF2)数据进行处理，分析NmF2的半年变化特征；将2018-08-26磁暴当天与宁静日的电子密度作差值，分析电子密度对磁暴事件的响应特征.结果表明：TBB观测数据能够有效监测电离层变化，正确反映站链上空电离层变化规律；在磁暴事件中，观测到了电子密度的变化过程，其准确地反映了正暴相的特征，证明在重要天气事件中，这一手段能够获得较为准确的观测数据.

| Abstract: | Tri-band beacon (TBB) transmitter has been carried on the China Seismo-Electromagnetic Satellite (CSES), based on the ground-based receiving system, it can be used to provide a quick ionospheric tomography. The main purpose of this work is to check the application effect of the TBB payloads. The study shows that during 2018?2019, the semiannual variations of ionospheric F2-layer can be observed clearly in NmF2 data, and we also detected the ionosphere perturbations induced by the geomagnetic storm occurred on August 26, 2018, which has been proved to be a positive storm event using electron density data. All these results indicate that TBB observation can provide accurate observation data of the ionosphere and be used effectively to monitor the ionospheric changes during the space weather events. |
