摘要

最近的研究表明，在太阳X射线飞行期间发出的强烈X射线辐射中，电离层D区对卫星信号传播的影响不容忽视。在本文中，我们研究了太阳氢Lyα辐射的变化对全球导航卫星系统（GNSS）信号传播的影响，这种变化表现为D区电子密度的变化，以及该区总电子含量的变化。我们考虑一个太阳周期和一年中的变化，用平滑的每日太阳黑子数和一年的哪一天来表示。所获得的结果表明，对于在太阳周期最大值附近的时间段内由单个接收器记录的单个信号进行定位，D区对这些信号的影响是不可忽略的。

Influence of the solar hydrogen Lyα line on the GNSS signal delay in the ionospheric D-region

. Recent research indicates that the inﬂuence of the ionospheric D-region on the propagation of satellite signals cannot be ignored during the intense X-radiation emitted during solar X-ray ﬂares. In this paper, we investigate the inﬂuence of changes in the solar hydrogen Ly α radiation, which is manifested in variations of the D-region electron density and, consequently, the total electron content in this region, on the propagation of the Global Navigation Satellite System (GNSS) signals. We consider changes during a solar cycle and year, represented by the smoothed daily sunspot number and the day of year. The obtained results indicate that the inﬂuence of the D-region on these signals is not negligible for positioning with a single signal recorded by a single receiver during the period around the maximum of a solar cycle.
