论文摘要
电离层不规则研究是理解电离层物理和相关过程的重要方面，尤其是在低纬度区域附近。但是，在印度经度部门的不规则量表大小的同时测量（利用navic和gps的L波段信号）尚未得到广泛解决。为了解决这个问题，本文列出了北部EIA Crest附近的位置的低纬度电离层不规则性（Indore：22.52 $^\ Circ $ n，75.92 $^\ Circ $^circe $ e地理和磁性倾角和磁性倾角32.23美元使用印度导航系统，Navic和GPS L5信号C/N $ _O $变化来确定使用电源不规则性量表的范围尺寸使用电源光谱密度（PSD）分析，地理和磁倾角为21.69 $^\ circ $ n），使用印度导航系统，Navic和GPS L5信号C/N $ _O $变化来确定电离层不规则尺度大小的范围。研究期跨越2017年9月至2019年9月，在太阳周期的下降阶段涵盖了不安和安静的时间条件。观察表明，不规则性量表的大小范围约为500 m至6 km。 This study for the first time, shows the nature of the temporal PSD for ionospheric scintillation during varying solar and geophysical conditions, by measuring the irregularity scale sizes utilizing simultaneous observations from NavIC and GPS from locations near the northern crest of the EIA and in between crest and the magnetic equator, ensuring proper characterization of ionosphere over the geosensitive Indian subcontinent.
Ionospheric irregularity studies are important aspects for understanding ionospheric physics and related processes, especially near the low-latitude regions. However, simultaneous measurements (utilizing the L-band signals of NavIC and GPS) of irregularity scale sizes over the Indian longitude sector, has not been addressed extensively. To address this problem, the paper presents simultaneous characterization of low-latitude ionospheric irregularities over a location near the northern EIA crest (Indore: 22.52$^\circ$N, 75.92$^\circ$E geographic and magnetic dip of 32.23$^\circ$N) and a location (Hyderabad: 17.41$^\circ$N, 78.55$^\circ$E geographic and magnetic dip of 21.69$^\circ$N) between the crest and the magnetic equator, utilizing the Indian navigation system, NavIC and GPS L5 signal C/N$_o$ variations to determine the range of the ionospheric irregularity scale sizes using Power Spectral Density (PSD) analysis. The study period spans from September 2017- September 2019, covering both disturbed and quiet-time conditions in the declining phase of solar cycle 24. Observations show that the irregularity scale size ranges from about 500 m to 6 km. This study for the first time, shows the nature of the temporal PSD for ionospheric scintillation during varying solar and geophysical conditions, by measuring the irregularity scale sizes utilizing simultaneous observations from NavIC and GPS from locations near the northern crest of the EIA and in between crest and the magnetic equator, ensuring proper characterization of ionosphere over the geosensitive Indian subcontinent.
