摘要

用加拿大e-POP仪器收集数据，用无线电接收仪(RRI)和3轴磁强计(MGF)测量62.5 pt至65.536 μt范围内的电场(10 Hz至30 kHz)。电场测量显示，沿轨道变化的ULF(210赫兹)和VLF(14千赫)范围的波受到50公里外天鹅座卫星火箭发动机点火的干扰。这些观测结果提出了一些问题，包括:这些观测结果是天鹅座的吗?观察到的谐波是器质性的还是物理性的?等离子体波的产生和传播方式是什么?这些观测结果被用来推断电离层的自然和人为变化。

Composition of the Topside Ionosphere Determined from Plasma Wave Measurements Using the Radio Receiver Instrument on e-POP

Data were collected with Canadian e-POP instruments to measure electric fields (10 Hz to 30 kHz) with the Radio Receiver Instrument (RRI) and the 3-axis magnetometer (MGF) in the 62.5 pt to 65.536 μt range. The electric field measurements showed waves ULF (210 Hz) and VLF (14 kHz) range that varied along the orbit and were disturbed by the firing of the Cygnus satellite rocket motor 50 km away. A number of questions are raised by the observations including: Are the observations attributable to Cygnus? Are the observed harmonics instrumental or physical? What are the plasma wave generation and propagation modes? The observations are used to infer natural and artificial changes in the ionosphere.
